At Vancouver Welding Inc., we provide high-quality welding services for pressure vessels and structural steel. Our experienced team ensures every weld is strong, durable, and meets industry safety standards. Whether you need new fabrication, repairs, or reinforcements, we’re here to help.
Pressure Vessel Welding
Pressure vessels are essential in industries like oil and gas, manufacturing, and power generation. These containers hold gases and liquids under high pressure, so they must be built and welded with precision to prevent leaks or failures.
Our team specializes in fabricating and repairing pressure vessels, using advanced welding techniques to create leak-proof, high-strength welds. We ensure every vessel meets strict safety regulations, giving you peace of mind that your equipment is safe and reliable.
Structural Steel Welding
Structural steel is used in buildings, bridges, and industrial structures. Proper welding is crucial to ensure strength, stability, and long-term durability. At Vancouver Welding Inc., we provide expert welding for:
We work closely with contractors, engineers, and project managers to deliver structural steel welding that meets safety standards and project requirements.
Pressure Vessel Welding Processes
Pressure vessels are manufactured by bending and rolling of a steel plate, and then butt-welded at its ends. Welding is a critical step in the fabrication of pressure vessels. The material of pressure vessels is mainly carbon steel or stainless steel.
Following types of welding processes are employed in pressure vessel fabrication, which are as follows:
Flux Core Arc Welding (FCAW) & Metal Core Arc Welding (MCAW)
Semi-automatic wire feed welding process that can be used for pipe, structural, or miscellaneous fabrication.
Shielded Metal Arc Welding (SMAW) / Stick Welding
Often used during field welding, a reliable process used onsite for pipe or structural steel welding.
GTAW / TIG Welding
It is a versatile welding process that is suitable for all welding positions. It uses a non-consumable tungsten electrode. It produces the highest quality weld and has become a replacement for gas metal arc welding in pressure vessel fabrication.
TIG welding is mostly used where small welds are needed on stainless steel.
Factors Governing Pressure Vessel Welding Specification
There are different factors that you should take into account before selecting a particular welding process and welding parameters for a pressure vessel. These factors include:
Pressure Vessel Welding Inspection
Since pressure vessels are highly pressurized and can be dangerous if not properly welded, the inspection of welded pressure vessels is necessary to ensure the quality of welded joints.
Following pressure vessel welding inspection technologies are applied on pressure vessels:
X-Ray Inspection
This pressure vessel welding inspection technique can detect welding defects beneath the surface. It is an extremely expensive technique that is used for critical weld joints as in nuclear power plants.
Ultrasonic Inspection
This pressure vessel welding technique can detect surface as well as subsurface welding defects. In this technique, a high-frequency sound wave is detected through the base metal and the welded joint. When a wave hits a discontinuity in a weld joint, part of the wave is reflected back. In this way, a welding defect can be detected.
Both welding inspection technologies have pros and cons that need to be considered based on applicable standards and customer requirements.
