Welding in piping is a process where two faces of pipe edge are fused together by means of heat application. A complete welded joint can be referred to as a weldment. This is a permanent type of piping connection. The welded joint is a direct connection between the pipe, the structure of welding is simple, beautiful, and tidy.

This increased flexibility of the connecting face tends to cause an uneven load distribution in the welded joint. An important first step is to have selected the members in an HSS connection astutely. For truss‐type connections, the branch width‐to‐chord width ratio (β) should be relatively high (say 0.7 to 0.8), but still preferably ...

Arc welding is a type of welding process using an electric arc to create heat to melt and join metals. A power supply creates an electric arc between a consumable or non-consumable electrode and the base material using either direct (DC) or alternating (AC) currents. This article is one of a series of TWI frequently asked questions (FAQs).

the welding process and position of welding necessitate all-position capability. HSS are typically very clean and free of heavy mill scale and oxides, and therefore the welding process does not need the de-oxidizing capability that might be necessary for welding on hot rolled material. HSS are often painted with glossy paint, and processes that

What is TIG Welding? TIG Welding is a manual welding process that requires the welder to use two hands to weld. What separates TIG welding from most other welding processes is the way the arc is created and how the filler metal is added! When TIG Welding one hand is used for holding the TIG torch that produces the arc and the other hand is to add the filler metal to the weld joint.
