Mig Welding Copper Pipe

As a general rule of thumb copper under 2 mm should have argon gas and up to 160 a applied.

Mig welding copper pipe.

Keep pants over the top of work boots don t tuck them in. Whereas mig welding requires a preheating of 10 100 c and up to 240 amps of power with argon as its shielding gas. Avoid rolling up sleeves or pant cuffs as sparks or hot metal will deposit in the folds and may burn through the material. For example in welding copper with thickness of 5mm 0 196 inch tig welding requires a preheating of 50 c as well as shielding gas of argon helium and mix up to 300 amps of power.

If the copper is thicker you will need to adjust the gas and amp by applying helium and upping the. Depending on if you are using tig tungsten inert gas or mig metal inert gas and the thickness of your copper you will need to adjust the ratio of your gas and temperature. Since the predominant application of copper nickels is in the form of relatively thin walled pipe the gas shielded tungsten arc welding process known as tig or gtaw is frequently used both for joining pipe sections and for attaching fittings and flanges. It is often necessary to raise the temperature level of the sheet in an area of 6 0 to 12 0 in.

Personal protective equipment ppe helps keep welding operators free from injury such as burns the most common welding injury and exposure to arc rays. A welding procedure specification wps should be prepared in all cases. Copper and its alloys are widely used in construction especially. In welding copper sheets the heat is conducted away from the welding zone so rapidly that it is difficult to bring the temperature up to the fusion point.
