There is one situation when helium or a helium-argon mix makes sense for welding carbon steel:welding very thick material. The general rule is that you can TIG weld one-thousandth of an inch (.001) per amp. A 150-amp welder is suitable for 0.15-inch thick material, or about 5/32. A 250-amp welder can weld quarter-inch steel. High Quality Custom Construction Pipe, Structure Steel The Construction Welded Steel Pipe used in building structure has the characteristics of relatively simple process, which is divided into high frequency welding, submerged arc welding, resistance welding, welding, spiral welding, etc., and has a wide range of applications in civil construction, petrochemical, light industry and other departments.

We stock a large inventory of high-quality stainless steel welded pipe. Our 304 and 316 stainless steel welded pipe meets and exceeds today's strict certifications. ASTM A312 stainless steel welded pipe has a resistance to corrosion and maintains strength at high temperatures. Stick Welding- Creating High Quality Stick WeldsLastly, high carbon and low-alloy steel plate can best be welded with the work in the level position. 3. Follow Simple Principles for Joint Geometry and Fitup Joint dimensions are chosen for fast welding speeds and good weld quality. Proper joint geometry is based upon some simple principles:Fitup must be consistent for the entire joint.

Advantages of welded steel pipes. Welded steel pipe can improve material utilization, simplify manufacturing process, and save steel and processing time. It can be processed into welding, bending and flanging. Welded steel pipe has high precision, uniform wall thickness and high brightness of internal and external surfaces. Welding steam pipe AWS Welding DigestOct 18, 2019 · The demand for quality in these safety-critical joints is reflected in the stringent regulations laid down in welding procedures. Nevertheless, some welding practices can result in a significant reduction in corrosion resistance and mechanical strength. Welding of high-pressure steam pipe welding steel - welding carbon steel - welding mild steelWelding steel is pretty fundamental to learning to weld.. Steel is basically Iron and Carbon with small amounts of other stuff like manganese.Low Carbon Steel has .3 percent carbon. Not 3 percent but 0.3 percent or point 3 percent. Thats not much. For comparison sake, Cast iron has a full 3 percent and sometimes more.
Welding Processes Obviously the first step in the welding of pipe is to run the root pass. This is perhaps the most critical pass on a pipe weld for several reasons. First, this is the most difficult pass to make on a pipe weld, requiring good operator skill for manually applied processes, with good process control combined with good alignment.
