A Welding Buyer's Guide

The Welding Process

Welding is a process for joining or fastening two pieces of similar metals (workpieces) by melting and fusing 1) the base metals being joined and 2) the filler metal applied. Most commonly, workpieces are welded by melting both of them and adding more molten metal or plastic to form a pool that cools to form a strong joint. The energy to form the joint between metal workpieces most often comes from a flame (e.g. oxy-acetylene) or an electric arc. Most welding involves ferrous-based metals such as steel and stainless steel. Welding covers a temperature range of 1500º F - 3000º F. Weld joints are usually stronger or as strong as the base metals being joined.

Whereas soldering uses solder, a lower-melting-point material, welding applies enough heat to melt the materials being joined.

Plasma Cutting

Plasma cutters are perfect for cutting and fabricating metal — from thin sheets, to thick beams. Plasma cutting employs a torch which uses a powerful electric arc to create plasma, made by boosting a gas (nitrogen, argon or oxygen) to a very high temperature. This creates a stream, or cone, of directed plasma that can reach a temperature of 30,000°F. Handheld torches can usually cut up to 1/2 in (13 mm) thick steel plate, and stronger computer-controlled torches can pierce and cut steel up to 12 inches (300 mm) thick. Unlike laser-cutting, for example, the process of plasma cutting is only effective on materials that conduct electricity.
