Industrial Automation Led by Advanced Technology in Arc Welding Processes

With advancements in the field of industrial automation taking over welding processes like never before; mere training from educational institutions (as well as basic hands on practice) is not enough. Whether it is about manufacturing pressure devices, sensors, metal seals, or other metal components; sealing, shaping, and/or joining techniques require precision welding which need to be extremely reliable, to maintain integrity of each product.

Welding professionals and others linked to the manufacturing industry need to stay in tune with technology-especially with regards to the latest trends related to arc joining processes. Read on for more.

MIG and TIG Weld Processes

MIG and TIG are the two popular methods used for precision joining; they offer acceptable weld quality on diverse metals, materials and alloys. Repeatability, in sync with the advances in process controls, power supply, and bonding techniques allow the use of these processes in many precision applications.

Advanced Techniques of Arc Welding

Pulsed arc welding techniques are used for providing low heat inputs for welding thin metals or components with fragile materials like glass or polymer. The process incorporates rapid increasing and decreasing of arc welding current; which in turn creates a seam weld with overlapping spot welds that reduces heat inputs to specific areas and increases the weld speed, overall output, and performance quality. The advantages of this technique are further enhanced by the rapid responses meted out by weld process controllers and power supplies.

Trends in Welding

Power Supplies

With refinements in welding power supply coming into the fray, application of forceful power to joining arcs is now passé. To cater to the requirements of superior quality, welders are now using high performance machines that boast of greater efficiency, response time and accuracy (to replace the earlier “beasts”).

Welding Control Systems

Stricter standard controls and rigorous quality demands have introduced weld programming devices which are capable of storing and executing diverse programs. These programmers/ controllers bring about reductions in scrap parts by implementing pre-arranged, repeatable, weld programs that are effectively controlled by precise bonding limits; therefore resulting in fewer errors.

Orbital Welding Systems

Orbital welding systems are designed for welding applications where space restrictions limit the access of joining devices or where tubes/pipes cannot be easily rotated. These are increasingly being used by industry verticals linked to boiler tubing, aerospace, food and dairy, pharmaceutical, nuclear and semiconductor.

Tungsten Electrode Material

TIG and plasma welding processes use welding electrodes with Thorium, a low-level radioactive element, to improve upon their arc welding and starting characteristics. Lanthanated electrodes, with new Tungsten materials, offer safer arc welding characteristics because of their lack of radioactivity and are now available commercially.

Tungsten Electrode Grinders and Pre-Ground Electrodes

Welding applications devoid of Thoriated electrode radioactivity problems and taking care of the requirements of consistency, repeatability and better weld quality, are offering the following benefits to manufacturing companies.

  • Increased arc stability, improved arc starting, and consistent weld penetration
  • Longer electrode
  • Minimization of Tungsten inclusions in welding
  • Use of dedicated electrode grinders to make sure that welding electrodes are not contaminated by the residue left on standard shop grinder wheels

These techniques and equipment in the welding industry are giving rise to better results and higher profitability!
