Tips for Troubleshooting Common MIG Weld Defects
Aug 19 It s caused primarily by improper welding gun angle or incorrect travel speed Avoid this problem by maintaining a 0 to 15 degree gun angle during welding and keeping the arc on the leading edge of the weld pool It s sometimes necessary to increase travel speed to maintain correct arc position
What should the pressure be on a MIG welding machine
If you have a small mig machine less than amps start at 15cfh and adjust from there to little and you will get a bad weld and to much you will get a bad weld The OP must have the double pressure gauge type of flow meter One gauge tank pressure one gauge regulated pressure
Resistance Welding Overview SWANTEC
Resistance welding is a welding technology widely used in manufacturing industry for joining metal sheets and components The weld is made by conducting a strong current through the metal combination to heat up and finally melt the metals at localized point s predetermined by the design of the electrodes and or the workpieces to be welded
