焊接的基础知识一、精密电阻点焊使用金属材料制作零件的场合，有许多时候都需要将材料切断成规定的尺寸，再将其连接起来。

连接材料的方法有利用铆钉进行机械连接和利用焊接进行冶金连接以及利用超声波进行物理连接。

电阻点焊是利用冶金的方法将金属材料高效率地经济地连接起来的一种方法。

因此在产业界被广泛地使用。

我们将精密小型工件的电阻焊接称之为精密电阻点焊。

米亚基公司源源不断地开发出各种超小型、可高密度安装化的新型精密电阻点焊机，取代了以往的锡焊、铆接等金属连接工艺。

精密电阻点焊机是最适合用于小型的、性能要求高的电子部品，以及精密机械工业中的小型部品的组装。

电阻焊接的原理利用焦耳热进行焊接Q=0.24I2Rt=0.24IEt(cal)…①公式①如下图所示，工件在上下电极间被加压，通电，进行电阻焊接。

焊接部的电阻为R（Ω），焊接电流为I(A)，通电时间为t(sec）时，根据公式①焊接部发热。

因此焊接部的温度上升，产生熔融。

图1二、电阻点焊的5大要素1、电流2、时间3、加压力4、电流密度（电极先端直径）5、电极材料上述要素与发热量Q及发热位置有关系，也就是说点焊时影响焊接效果的因素有：电流I、通电时间t、接触电阻R、电流密度（电极先端）和电极材料。

接触电阻R随着加压力的增大而降低。

以上要素被称为电阻点焊的五大要素。

接触电阻工件表面生成的氧化薄层引起的电阻（表皮电阻）和由于电流的流通截面引起的电阻（集中电阻)。

图2上图中，R2,R4……材料自身的电阻；R3……上下工件之间的电阻；R1,R5，……电极与工件之间的电阻。

接触电阻是指R1、R3、R5。

三、电极的作用1．导通大电流。

2．施加压力。

3．提高焊接点的冷却效果。

4．稳定电流密度。

电极具有以上的作用，这里解释一下与品质管理有关的电流密度。

电流密度是指单位横截面中的电流值。

如果将电流密度一直保持稳定，就能防止焊接不良。

由于要导通大电流（电极作用1)，电极顶端会发热；又由于要加压会使电极顶端变宽，电流密度变小，因此，随着焊接次数的增多，焊核会变小（焊接不良）因此在焊接品质管理中电极的管理（进行一定次数的焊接后更换或修磨电极）就变得非常的重要。

The materials are subject to current control and quality supervison and then processed and mounted together into MIGATRONIC welding machines.No matter how good materials we have used and no matter how carefully the mounting has been done, an advanced product as a MIGATRONIC MIG-MAG-welding machine demands your effort to operate perfectly for years.Therefore study carefully this instruction before your initial operating. This should assure a profitable use of your new MIGATRONIC welding machine.CONGRATULATIONS!GENERAL DESCRIPTIONMIGATRONIC welding machines, type Automig: 140 Mono X, 140 X, 180 Mono X, 180 X, 185 X, 200 X, 250 X and 300 X have been developed for thin plate welding and car body repair.The Automig 140 Mono X and 180 Mono X are designed to normal single-phase 220-240 V plug (F+0+earth)/10 Amp(16Amp) where as the Automig 140 X, 180 X, 185 X, 200 X, 250 X, 300 X are designed for three-phase 220-380 V (3F+earth)/10Amp.Automig 185 X needs only two phase wires (2F+earth)/16Amp.The main parts of the machine are the main transformer, the contactor, the rectifier for welding current, the condenser battery (only 140 M X, 180 M X, 185 X), the control transformer, the wire feed motor, the solenoid valve and the electronic control.The welding transformer has been dimensioned to obtain optimum welding capacities, and for a working temperature of 180°C. For further protection a thermal fuse has been incorporated which automatically cuts out the machine at 150°C. The overheating protection will switch on automatically when the transformer has cooled. The rectifier is electronically protected against overloading in case of short circuit of the welding current, the machine will cut out after approx. 3 sec.Mode of operation: When the trigger at the welding handle is activated the contactor will couple voltage to the welding transformer which will give a secundary voltage decided by the position of the voltage switch. In the rectifier this AC voltage is transformed into a DC voltage which is applied between welding torch and return cable. At the same time the flow of protection gas and the wire feed motor are started. The number of revolutions is decided by the adjustment button. When you lift your finger from the trigger the motor will stop and after a short delay the contactor and the welding current are interrupted.This delay which is called "burn back delay" has the effect that the welding wire will burn back a little from the molten pool and thus does not stick to the pool. The time of delay can be set by the lowest trimpotentiometer at the print card.The electronic control can be set to the functions "seam" , "spot" , and "interval" .At "seam" the welding will start when you press the trigger and stop when you release the trigger.At "spot" the welding will stop after a delay that can be set by the button "welding time". Using this function you are sure of a uniform interval welding.In the position "interval" the wire feed motor will stop with intervals that can be set by the buttons "welding time" and "pause time". When you put "pauses" into the welding, the average heat volume added is reduced to prevent a burning through on difficult welding tasks.INITIAL OPERATINGMains connection:Input voltage should be as stated on the type plate of the machine. If dual voltage, the tapping must be checked before mains connection.Shielding gas connection:The shielding gas bottle is mounted on the machine and the regulator on the bottle. If the regulator is equipped with flowmeter, the gas quantity is adjusted on 5-15 litres/min.Welding hose connection:The welding hose is put through the hole in the front plate and into the switch on the wire feed console (see page 11). Keep the inlet nozzle as close to the wire feed roller as possible without letting them touch each other. Fasten the Allen screw and mount the gas hose and the control wire. Check that the hole in the inlet nozzle is in line with the groove of the wire feed roller.Fitting the welding wire:Turn the tension spring aside and tip it up. Check that the wire feed roller, the wire guide liner and the contact tip correspond to the wire diameter, the wire feed roller is designed for two wire dimensions and should be turned around until the outer side is showing the wire size being used. The following wire guide liner is recommendedWIRE DIAMETER FE.WIREmm WIRE GUIDE LINER INT.DIAM.mmø 0.6ø 0.8 - ø 1.0 ø 1.0 (ø 1.5)ø 1.5WIRE DIAMETER AL.WIREmm WIRE GUIDE LINER INT.DIAM.mmø 0.8 ø 1.0 ø 1.5 ø 1.5When using aluminium wire use a special guide liner where the internal liner goes all the way through the inlet nozzle. This prevents the aluminium wire from being damaged.The reel of wire is put on the hub, and the wire is put through the wire feed unit and some centimeters into the hose. As the wire guide liner is vulnerable to burrs at the point of the wire, it is important to file the point of the wire in order to remove all burrs and it is equally important to straighten out the first 10-15 cm. Unscrew contact nozzle. Tip up the lever. Set the wire speed at 6, press the start button, the wire runs through the hose. When the wire is through the hose, stop the machine and mount the contact nozzle. The pressure of the lever is adjusted to allow the wire feed roller just to slide on the wire when this is stopped at thecontact nozzle.Automig 185 XThe special welding hose is mounted at the quick clutch of the machine and the Jack-sleeve and the welding handle is mounted with the desired electrode holder.For planishing of dents with carbon the voltage switch of the machine shall be set at step 8 whereas voltage step 7 is used when welding nails or discs. Using this method it is important for a satisfactory result that you do not press the handle too hard against the workpiece as the contact resistance between nail (discs) and the piece is reduced and the desired generation of heat is decreased.You must also take care that the return clip is in good contact with the piece and is not attached too far from the welding point.CONTROL SWITCHES/INSTRUCTIONS1. Welding time: With this switch the welding time is chosen, when 2 is in position: interval and spot.2. Switch:Seam:The switch is set at seam. The trigger on the welding handle is activated, welding starts. By letting go the trigger you stop the welding process.Spot:The switch is set at spot. When the trigger on the welding handle is activated, welding starts. Welding automatically stops, depending on the time adjusted by button 1 (0.2-1.5 sec.)Interval:The switch is set at interval. When the trigger is activated, welding starts. The welding automatically stops, depending on the time adjusted by button 1. After an interval fixed at button 3 the same cycle continues automatically and is only interrupted when the trigger on the welding handle is released.3.

Pilot cable for bolt welding hose (only at Automig 185 X).WELDING TECHNIQUESetting of the machineThe setting of a MIG-MAG welding machine demands some practice from the welder, the machine having two control points that have to conform. These two are the wire feed speed and the welding voltage. The welding current is determined by the wire feed speed, and it should correspond to the workpiece. The current will increase with increased wire speed, resulting in a shorter arc. Less wire speed will reduce the current and lengthen the arc. Increasing the welding voltage hardly alters the current intensity, but lengthens the arc. By decreasing the voltage a shorter arc is obtained with little change in current intensity.When using CO2 as shielding gas, increase the voltage by about 5 Volts per 100 Amp.When changing the wire diameters, different control settings are required. A thinner wire needs more speed to acquire the same current strength. A satisfactory weld cannot be obtained if extreme values are exceeded.If the feed speed is too high for the welding voltage, blockage will occur in the torch as the wire dips into the molten pool and does not melt. Welding in these conditions normally gives faults due to lack of fusion. If, however, the welding voltage is too high, large drops will form on the end of the wire, causing spatter.The correct setting of voltage and speed can be seen in an even and calm arc.See tables.Influence of the welding positionThe position of the torch and the work piece is important for the quality and appearance of the seam.The diagrams on the next page show some of the many possibilities and indicate schematically the importance of these positions. In practice one of course uses all combinations of welding positions, torch directions and positions of the work piece.Together with the figures, the diagram below may help when an estimation of the importance of separate factors for welding quality is needed.The terms drawing weld and thrusting weld mean:Drawing weld:torch sloped in direction of weldThrusting weld:torch sloped away from direction of weld.Drawing weld is sometimes designated "dragging welding" and thrusting weld "stabbing" weldingThrusting weld Drawing weldWidth of seam wider narrowerUpper bead smaller largerPenetration decreaseincrease Tendency to lack of fusion greater lesserMAINTENANCEThe following items demand special attention:Wire feed unitThis unit is to be checked regularly at the wire feed roller and the wire nozzles, as it is of great importance for a satisfactory welding result and a minimum of wear and tear that the wire passes through the mechanism without any deformations of the wire or the wire feed roller.The wire nozzles should often be checked and changed if the copper coating of the wire is damaged on its way through the nozzles. Copper dust may totally hinder free passage through the wire liner.A weekly check and cleaning of the nozzles as well as the wire feed roller is recommended.Welding hoseGreat care should be taken that the welding hose is not overloaded. It should not be pulled over sharp edges, and other heavy machines should not run over it as it may damage the wire lines. The hose should be dismantled every week and blown out with dry air.Welding torchThere are many parts in the welding torch that have to be cleaned regularly. The main ones are the contact tip and the gas nozzle. During the welding process, these parts are bombarded with spatter that sticks in the nozzles. This may disturb the shielding gas flowing from the gas nozzle down to the molten pool. Otherwise, if the gas nozzle is blocked up with spatter, there is a danger that a short-circuit will occur between the contact tip and the gas nozzle. The spatter should therefore be removed regularly and spatter remover applied in order to prevent spatter from burning into the nozzles. During the cleaning process, the gas nozzle should be removed.DO NOT CLEAN BY BEATING THE TORCHPower sourceThe rectifier and transformer should be blown out with dry air occasionally, otherwise the air circulation will be affected by the dust.FAULTSFAULT:Too little welding effectThe welding seam forms a bead. PROBABLE CAUSE:1. One of the three fuses in the main switch is notworking (one phase is missing).2. The welding voltage is too low.Switch one setting higher.The wire feed is blocking. 1.
