Welder Training Courses in Bangalore — TIG, MIG (GMAW), Arc (SMAW) & FCAW

The best welder training course is the one that matches your target process and job, and is delivered by qualified trainers, on modern machines, with weld inspection and code-based qualification. When comparing institutes, check: (1) is training mostly practical, (2) are welds actually inspected by NDT, (3) can you qualify to ISO 9606-1 or ASME IX afterward, (4) are trainers IWE, CSWIP or AWS certified, and (5) are the machines current. Trinity NDT’s Centre of Excellence in Welding in Peenya offers all five.

Trinity NDT offers welder training in four processes: SMAW (arc/stick), GTAW (TIG), GMAW (MIG/MAG/CO₂) and FCAW (flux-cored). Programmes cover plate and pipe, are customised to your job, and can be followed by a welder qualification test.

MIG welding feeds a continuous wire electrode automatically and is faster and easier to learn, while TIG welding uses a non-consumable tungsten electrode and a hand-fed filler rod, giving cleaner, more precise welds but requiring more skill and time. MIG suits production fabrication; TIG suits critical piping, stainless steel, thin sections and aerospace work.

GMAW (gas metal arc welding) is the umbrella term for MIG and MAG welding. It becomes MIG when an inert gas such as argon is used and MAG when an active gas such as CO₂ or an argon-CO₂ mixture is used. In India, CO₂-shielded GMAW on steel is often just called “CO₂ welding”.

SMAW (shielded metal arc welding), also called arc welding or stick welding, joins metals with an electric arc struck between a flux-coated electrode and the workpiece. The flux coating burns to produce a gas shield and slag that protect the weld, so no separate shielding gas is needed.

TIG welding is used where weld quality is critical — pressure vessels, boilers, process piping, stainless steel systems, aerospace parts and thin materials. It produces clean, high-quality welds and is widely used for root passes on pipes.

FCAW (flux-cored arc welding) uses a tubular wire filled with flux, while MIG uses a solid wire and always needs external shielding gas. Self-shielded flux-cored wires need no external gas, which makes FCAW well suited to outdoor and structural work.

SMAW (arc welding) is the best first process for most welders because it teaches arc control, joint preparation and defect awareness with low-cost equipment. Add TIG for pipe and stainless steel work, or MIG/MAG and FCAW for high-production and structural fabrication.

Duration depends on the process, the positions you need and your prior experience, so we tailor it for each candidate or batch. Most programs for welder training runs for about  2 – 8 weeks.

Fees depend on the process, duration, consumables and whether a qualification test is included. Share your requirement on WhatsApp (+91 9844129439) and we will send a quote. Our welder training strarts from Rs.20,000/-

We recommend at least 3 months of on-the-job welding experience so you can absorb the practical training quickly. In special cases, freshes and ITI pass outs can join foundation batch. Corporate groups can be trained irrespective of level, with the content matched to their skill.

You receive a training completion certificate after the course. A welder qualification certificate is different: it is issued only after you pass a test weld as per a code such as ISO 9606-1 or ASME Section IX, and it is the document employers and inspectors check. We can arrange the qualification test after training.

Under ISO 9606-1, a certificate is valid for three years, provided the employer confirms every six months that the welder has continued to weld within the qualified range. Under ASME Section IX, qualification stays effective as long as the welder uses the process at least once every six months. Always check the current edition of the code or your client’s requirement.

The 6G test is a pipe welding test in which the pipe is fixed at a 45° incline and cannot be rotated, so the welder must weld through flat, vertical and overhead positions in one joint. Passing 6G is a widely recognised proof of pipe-welding skill and typically qualifies the welder for all positions on pipe and plate, subject to the code’s rules.

A WPS is the approved welding procedure the welder follows, a PQR (or WPAR/WPQR) is the record of the qualifying test weld and its results, and a WPQ is the qualification record that proves an individual welder can produce sound welds to that WPS. Trinity NDT prepares all three and tests the welds in its NABL-accredited laboratory.

Yes. Trainee and qualification test welds can be inspected by visual testing, radiography (X-ray and gamma ray), ultrasonic testing, magnetic particle inspection and liquid penetrant inspection at Trinity NDT’s own laboratory, and by mechanical tests where the code requires them.

Yes. We can train groups at our Peenya centre or at your premises, with the content designed around your WPS, materials, thickness range and welding positions. We regularly serve clients in Bangalore, Mysuru and the Hosur area.

Yes. Welders trained elsewhere can take a qualification test at our centre, and companies can have their welders qualified at their own site by our inspectors. See our welder qualification test page for details.

The centre is at 491, Site No. 12, 14th Cross, 4th Phase, Peenya Industrial Area, Bangalore – 560058. You can reach us at +91 98441 29439 or info@trinityndt.com.

Yes — India’s expanding manufacturing, fabrication, energy and infrastructure sectors have created strong demand for skilled, certified welders, and demand is highest for welders who can qualify in TIG and pipe welding to international codes. Skill and certification, more than formal education, decide employability and growth.
