Category: Welding & Cutting

When I started assembling my cutter, I began with taking a good look at my parts list, later in this article. Once this was accomplished, I would study each the parts pictorial to get familiar with each part/component and they would be placed. The next step was to study my schematic and create a layout…

I use this stand when cutting long lengths of material on my power hacksaw. By making two stands, they can be used to support material during welding. Kind of an adjustable sawhorse. MATERIAL LIST FOR STAND SHOWN ( ALL MATERIAL MILD STEEL ) 1 – 1″ diameter black pipe X 18″ long. 1 – 2″…

I needed a small metal table that I could carry around to various jobs to use for holding weldements and for cutting. I wanted the table to be small enough to be easily carried and put into the back of my truck, but strong enough to hold heavy metal parts for welding and cutting. I…

Introduction   Explosive welding is a solid state welding process, which uses a controlled explosive detonation to force two metals together at high pressure. The resultant composite system is joined with a durable, metallurgical bond. Explosive welding under high-velocity impact was probably first recognized by Garl in 1944. Explosive welding was first recognized as a…

INTRODUCTION The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets below the water line. Underwater welding is an important tool for underwater fabrication works. In 1946, special waterproof electrodes were developed in…

The purpose of this page is to introduce the beginning welder to the equipment used in the Oxy-Acetylene welding process. This will be done starting with the cylinders and ending with the torch tip. BACKGROUND The use of gas welding dates back to the middle 1800’s where a mixture of Oxygen And Hydrogen were used…

INTRODUCTION There are many different types of electrodes used in the shielded metal arc welding, (SMAW) process. The intent of this guide is to help with the identification and selection of these electrodes. ELECTRODE IDENTIFICATION Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16…

As you can probably imagine welding; either with a torch or an arc; is a skill that takes much skill and knowledge to do well. That having been said I would like to give a summary of some of the basics of gas torch welding. There are two broad classes of gas torches: Air-Fuel Oxy-Fuel…

Welding certifications are procedures that a welder must follow to produce a sound weld according to the guidelines that are specified. The certification is a hands-on welding test, supervised by an individual that is trained and approved by the certifying organization. These tests or certifications only qualify the welder for a single process and position.…

TIG Welding Names TIG Welding, or TIG, is an acronym for “Tungsten Inert Gas” welding. TIG is a commonly used and accepted slang term. The proper terminology is “Gas Tungsten Arc Welding” or GTAW. This is the term used by welding engineers on blueprints, and in welding procedures. When TIG was introduced around the 1940’s…
