Welding Operations

The facility possesses an extensive inventory of welding equipment, categorized by welding process:

• semi-automatic gas-shielded arc welding (MIG/MAG);
• gas tungsten arc welding (TIG);
• manual metal arc welding (MMA);
• robotic gas-shielded arc welding;
• submerged arc welding (SAW);
• resistance spot welding (SW);
• thermal spraying (metallizing).

A wide range of welded joints and metal/alloy surfacing operations are performed.

A wide range of welded joints and metal/alloy surfacing operations are performed.

• high-carbon, low-alloy, thick-walled steels (such as 30, 40, 35G, 35KhGSA, 40KhNS, etc.);
• alloyed chromium-nickel steels (such as 12Kh18N10T, 12Kh18N9T, 08Kh18N10T, 20Kh23N18, etc.);
• alloyed chromium-molybdenum heat-resistant steels (such as 12Kh1MF, 12KhM, 12Kh2MFSR, etc.);
• titanium alloys (such as VT1-0, OT-4, etc.);
• nickel alloys (such as KhN32T, KhN78T, etc.);
• aluminum (such as AMg2, AMg6, etc.);
• bronze (such as BrKMTs, BrAMts, etc.).

In our view, submerged arc welding is unique, as it allows for the welding of longitudinal and circumferential seams on cylindrical shells—without the need for edge preparation or a separate root pass—by using a flux backing.

Another advanced method we employ is robotic welding, which performs welding in a shielding gas environment according to a pre-set program. This approach minimizes the need for operator intervention, thereby eliminating human error and ensuring a straight, uniform weld bead. The width and reinforcement of the weld comply with the GOST 14771-76 standard, featuring a smooth transition to the base metal.
