152 4 to 304 8 mm away from the weld.
Mig welding copper pipe.
Use the proper gas ratio.
Avoid rolling up sleeves or pant cuffs as sparks or hot metal will deposit in the folds and may burn through the material.
If the copper is thicker you will need to adjust the gas and amp by applying helium and upping the.
Keep pants over the top of work boots don t tuck them in.
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.
As a general rule of thumb copper under 2 mm should have argon gas and up to 160 a applied.
Whereas mig welding requires a preheating of 10 100 c and up to 240 amps of power with argon as its shielding gas.
In this video rob will go over how to properly tig weld copper tubing with silver solder.
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.
Personal protective equipment ppe helps keep welding operators free from injury such as burns the most common welding injury and exposure to arc rays.
Copper and its alloys are widely used in construction especially.
It is often necessary to raise the temperature level of the sheet in an area of 6 0 to 12 0 in.
