From H-beam assembly lines producing 40T per day to gantry welding systems for box columns and frames — WXABK delivers the automated welding equipment that keeps structural steel fabricators competitive in Canada and globally.
Shipbuilding and marine fabrication is one of the most demanding environments in heavy industry. Whether you are building offshore supply vessels, bulk carriers, naval patrol boats, or steel barges, every pipe spool, hull section, and structural assembly must meet strict classification society standards — Lloyd’s Register, DNV GL, Bureau Veritas, or ABS — with zero compromise on
weld quality.
The volume and variety of welded components in a single vessel build is immense. Pipe spools alone can number in the thousands. Each must be fitted, welded, inspected, and tracked. WXABK welding rotators, positioners, and pipe spool fit-up stations automate the rotation and positioning of every cylindrical or asymmetric weldment — keeping joints in the flat position and throughput consistently high throughout the build programme.
A typical pipe spool fabrication workflow using WXABK fit-up rolls and welding rotators in a marine prefabrication shop.
Pipe sections are aligned on WXABK fit-up rolls where operators set the joint gap, check alignment, and tack-weld the joint. The rolls hold the pipe steady and rotate it for full circumferential tack access.
The tack-welded assembly is transferred to the welding rotator. The operator sets the rotation speed to match the welding travel speed. The pipe rotates continuously while the welder or SAW torch remains stationary at the top — flat position.
Welding heat distorts the flanges. The straightening machine applies hydraulic pressure to restore the flanges to within code-required tolerances automatically.
The completed spool is removed for NDT inspection. With consistent flat-position welding on every joint, rejection rates drop significantly and the spool proceeds to the assembly area on schedule.
A pipe spool prefabrication facility supporting a major Canadian shipyard was struggling to meet their contracted weekly spool delivery targets. With manual fit-up and welding on every joint, their team of 10 welders was producing approximately 120 spools per week — well below the shipyard’s requirement.
"We hit 170 spools per week in the first month and haven't missed a shipyard delivery since. The rotators paid for themselves before our first warranty inspection."

These are the welding production and quality challenges shipbuilders and marine fabricators tell us about most — and how WXABK equipment addresses each one.
A single vessel build requires thousands of individual pipe spools across dozens of pipe systems. Manual fit-up and welding of each spool is extremely time-consuming, creating schedule pressure across the entire build programme.
Every weld on a classified vessel must meet the requirements of Lloyd’s, DNV GL, BV, or ABS. Welding in positional (overhead, vertical) orientations due to poor positioning equipment increases the risk of defects that fail NDT inspection.
Crane pedestals, shaft brackets, rudder frames, and deck equipment bases are large, asymmetric weldments that are difficult to position for optimal welding access with manual methods.
Interior seams on large pipe sections, sea chests, cofferdam structures, and hull block intersections are often inaccessible with handheld equipment without costly confined space procedures.
Qualified marine structural welders with classification society certification are expensive and increasingly scarce in Canadian shipbuilding regions. Manual processes amplify the labour cost per weld metre.
Marine classification societies require full welding procedure traceability, WPS/PQR compliance, and welder qualification records. Inconsistent manual processes make documentation difficult and audits stressful.
