Gas Metal Arc Welding (GMAW) has established itself as a high deposition welding process, bringing in tremendous benefits of higher productivity and economics over MMA welding. Full utilisation of these advantages have not been possible in the past, due to limitations in the conventional equipment and controls used for the process. Also, conventional equipment are not compatible for mechanised or automated welding applications.
Recent innovations, particularly transistorised power blocks, special wire drives and controls, have now added a new dimension to the GMA welding process, helping to increase productivity and quality, while retaining process economics with these units, it is possible to have total control over the metal transfer mechanism in GMA welding. Process variations like Plasma-MIG welding and Synchro-Pulsed-MIG welding, which give much higher productivity and process flexibility are now practically viable with these units. On line mechanisation and automation of the welding cycle become straight forward and simple.
This paper outlines these innovations in equipment and brings out how they have helped GMA welding process in steadily replacing MMA welding, as the most universal arc welding process.

In the majority of common welding processes, the welding variables viz. arc voltage, wire feed speed or current, travel speed and the torch to work distance are preset manually by the welder or supervisor. This presupposes that enough is known about the material and the process for all the many parameters to be preset to their optimum values.

The use of greater plate thicknesses in the new aerospace and hydrospace materials has increased the need for new, high speed, high quality welding processes. Conventional methods to weld these materials have serious economic limitations because of low speed. Recent developments, such as plasma arc and electron beam are being utilised to some extent, but conventional tungsten inert gas welding remains the most widely used process where weld quality is very important. Within the last decade, many refinements have been made to increase the speed of welding with TIG process, the most important one being its automation.- From the Joint Editor's Pen

Dear Members,
Warm Greetings to you.
The second issue of the Indian Welding Journal printed in Bangalore is in your hands. We apologise for the delay in releasing the same, but we thought that National Welding Seminar at Baroda will be a memorable occasion to bringout the issue.

Dear Members,
Warm Greetings to you.
The first issue of the Indian Welding Journal printed in Bangalore is in your hands.
As you are aware, IWJ has been published from H.O Kolkata all these years. The Editorial team has been striving hard to make the journal excellent in its appearance as well as content. Our sincere thanks to the editorial team for their untiring efforts. For quite some time, our Council has been toying with the idea of giving the responsibility of bringing out the IWJ to various branches by rotation. The idea is to make use of the talent available at branch level and also share responsibilities with the H.O. We are happy that the Bangalore branch has been chosen to carryout the experiment. The next four issues will be brought out from Bangalore Branch.

Dear Members,
Warm Greetings to you,
You are receiving the joint issue of July and October now. Although, we are able to lay hands on good research papers and useful articles for publication in IWJ, getting sponsorship help from the industry has been very difficult. While a lot of efforts have been put in contacting all major industries and distributors in the welding field, very little response has been received. It is a matter of concern for all of us that IWJ which is the main medium of communication with our members is not self sustaining. The resources of our Institute is also very small and unless good industry support is available, IWJ will keep suffering. On behalf of the central council, I request all the members to come forward and support IWJ.

Dear Members,
Warm Greetings to you,
World’s largest democracy, India, has completed one more General Election and a new government under the leadership of Dr. Manmohan Singh is in place. The regime of liberalisation started in 1991 when Dr. Manmohan Singh was the finance minister and we hope the industrial segment in the country will show good growth under his leadership as Prime Minister.

Dear Members,
Warm Greetings to you.
At the outset, we would like to sincerely apologise for the long delay in bringing out the January, 2004 issue of our Journal. While we had all technical matter ready, we had to put lot efforts to get financial support for bringing out the issue. As all of you are aware, funds for bringing out IWJ comes only from advertisements. We need at least Rs. 50,000/- to bring out each issue. I appeal to all the Industrial members and other Industrialists to help the Institute with advertisements.
