[2] reported that the use of pulsed arc welding in place of conventional GTAW increases the output by 200–400%‚ reduces consumption of argon by three to ten times‚ and also reduces the cost of 1 m weld deposition by three to five times. The aim of pulsing is mainly to achieve maximum penetration

Welding caps help protect welders and pipefitters from getting burned from the welding sparks. Making and distributing welding caps has three basic steps‚ choosing your audience‚ purchasing items needed and then distributing them. Choosing the perfect audience is crucial in starting the process for making welding caps. The question to ask yourself is‚ who will purchase more. By narrowing

Global Welding Consumables Market 2014-2018 Welding is a process of joining similar metals together. It is one of the methods of making high-strength joints of two or more different parts. Filler metals melt with joining materials and are consumed during the welding process. Flux is used to produce a gas shield around the weld pool and to prevent the oxidation of hot metal. It acts as a deoxidizer and prevents the formation of porosity in the weld pool. Flux does not form the final part of welding

PROS AND CONS OF UNDERWATER WELDING To briefly present the advantages and disadvantages of underwater welding let us first separate this two compound words‚ the UNDERWATER and WELDING. Underwater is anywhere where this is water‚ either in low or in deep aquatic areas. Now‚ Welding is the action of burning something (particularly a metal) into creating or fixing something with the use of a high temperature to burn down or melt a metallic material so that it can be reformed. Combining this two concepts
