With more than 30 years of experience in the welding industry and over 8 years experience in trading industry, Mr. Raj Kumar Mittal, the founder & Managing Director of Mitco Weld Products Pvt. Ltd., initiated the brand “ARCON” in the year 1990 with a vision to provide welding solutions to the industry by virtue of quality welding products and associated services.
In order to further add to the customer experience, here we start the ARCON BLOG that will share our knowledge, experiences and views about welding product industry. This would everything & anything from which product to use, to tips on how to use the products more efficiently and also the latest trends in the industry.
So tune in to stay updated and make the best out of it.
Tungsten Inert Gas (TIG) or Gas Tungsten Arc Welding (GTAW) welding process is used where more weld strength is required & where fine weld finish is of utmost importance.
In TIG welding process, tungsten electrode is used as a media to create an arc along with suitable shielding gas. Now, here tungsten electrode plays a very important role. Since tungsten electrode is itself a very hard metal, it creates a very fine and stable arc resulting in strong and fine finish weld joint, which we mentioned above.
TIG welding can be done on any metal using suitable filler material. Here, one should be cautious while selecting the filler material. The filler material chemical composition should be as near as possible to that of the base metal. So ask for the composition chart from the supplier & match the same with the base metal composition. The benefit of similar composition would be that the weld pool created during welding would have atoms that would mix very easily thus, creating a strong weld joint.
Another very important aspect one should definitely consider while selecting filler material is that the same should be free from dirt (grease, oil, paint, sand particles, plastic contamination) and rusty metals and other forms of corrosion which may produce weaker weld joints (porosity and joint cracking) and makes the welding task difficult. Clean base metal is of equal importance.
ARCONfiller rods are surface treated using biodegradable chemicals for deep cleaning to remove all surface contaminants (even from pores) to produce strongest and more durable weld deposits. Mere spray water jet cleaning is not enough since it is not capable of deep cleaning. In short, the filler material should be of natural color as that of the raw material from which it is made. Surface shining is not of any importance.
