Metal inert Gauze, or MIG, welding is a organization of welding processes that employ a consumable wire electrode and a shielding Gauze.
Instructions
1. Choose the electrode. The width of the electrodes used in stainless steel pulsed arc welding typically ranges from 0.03 to 0.045 inches.
The pulsed arc transaction is a public MIG welding mode that uses a grand now pulse to transfer a Blop of molten metal across an arc. Stainless steel is a conventional expression that generally applies to any steel alloy that contains exceeding than 12 percent chromium. Most types of stainless steel are relatively easily done to MIG weld with a pulsed arc.
The Essay of the electrode Testament be generally consonant to that of the mannequin metal, although the electrode should melt at a lower temperature.
2. Alloy the shielding Gauze. Pulsed arc welding uses a shielding Gauze that's 99 percent argon and 1 percent O2. The chemical reactivity of this mini extent of O2 provides the more weld penetration that stainless steel requires.
3. Appropriate the pulse Closeness. MIG welding generally uses a average efficacy overhaul that delivers a fixed current. The pulsed arc process will need a special power supply capable of alternating between a high and low current. This technique typically uses a current frequency that pulses between 30 and 400 times per second.
4. Estimate the maximum current to use in pulsed arc welding. A chart is usually attached to each MIG welding machine that provides the specific current to use for each combination of electrode thickness and base metal thickness. The pulse arc mode generally uses less current than other MIG welding techniques.
5. Use a slower welding speed. Pulsed arc welding is somewhat slower than other MIG welding techniques and is normally limited to 200 inches per minute. This technique is best suited for a thin base metal, and the weld should generally be made with a single pass.
