Welding polyurethane foam-filled parts can produce toxic gases. Welding should not be attempted on parts filled with polyurethane foam. If repair by welding is necessary, the foam must be removed from the heat-affected area, including the residue, prior to welding.
 This is a hazardous procedure. The hazard to the worker is due to the toxic gases […]

In order for welding to be fully accepted as a tool in engineering, the passing of information from the architect of the design and the end user must be accurate and fully understood. One way of doing this is by using widely accepted welding symbols which enable design drawings to be completed with welding information. The […]

There are three basic welding methods: manual, semiautomatic, and automatic. Manual welding is the oldest method, and though its proportion of the total welding market diminishes yearly, it is still the most common. Here an operator takes an electrode, clamped in a hand-held electrode holder, and manually guides the electrode along the joint as the […]

Altogether, there are approximately 100 types of welding. When you learn to weld, you will learn the differences among them. Differences are due to the molecular nature of the materials, required precision, and environment in which the welding takes place. For example, a sculptor might use a gas flame to weld two pieces of metal […]

These cylinders contain Acetylene under pressure, are painted black, ( small “B” and “MC” tanks can be gray, silver or red ) made of steel and have cylinder valves. They range in size from 10 to almost 400 cuft capacity. The cylinders contain a porous filler material which is wetted with acetone that allows the […]

The purpose of this article is to introduce the welding beginner to the equipment used in the Oxy-Acetylene welding process. This will be done starting with the cylinders and ending with the torch tip.

CYLINDERS
Oxygen and Acetylene are stored under pressure in steel cylinders . They are sized by the cuft. of either Oxygen or Acetylene that […]

The use of gas welding dates back to the middle 1800’s where a mixture of Oxygen And Hydrogen were used to produce a hot flame that was used in the making of jewelry. It wasn’t until the late 1890’s when the gas Acetylene became available that gas welding developed into the process that we know […]
