Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Arc Welding Machines. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This automatic arc welding machine is intended for storage tank construction, including LNG tank projects and other tank erection work in oil and gas, refinery, offshore, and shipbuilding settings. The available equipment range covers girth seam, vertical seam, butt seam, and corner seam welding tasks.
For girth seams, the AGW configuration uses submerged-arc welding technology and can automatically weld inside and outside horizontal seams. Listed variants include machines for top-to-bottom construction and multifunction models for both bottom-to-top and top-to-bottom erection.
The standard girth welding machine is described for shell plate widths from 1.3 to 2.8 m. The vertical seam welding configuration is specified for tank wall thicknesses from 10 to 50 mm.
It includes a motor frequency-inverter drive, a weatherproof control box with a digital welding-speed display, travel speed from 0 to 2200 mm/min, and a beveled-gear drive reducer designed to lock in both directions. The EGW process uses flux-cored wire.
Butt and corner seam equipment is available for welding tank bottom plates and includes a magnetic idler system. The supplied information reports a first X-ray qualification rate above 99%.
It also states maximum efficiency comparisons of up to 30 times manual welding for AGW and up to 50 times manual welding for EGW;buyers should confirm the test basis, operating conditions, seam geometry, and production assumptions behind these comparisons.
Procurement teams should define the required seam type, erection method, tank diameter, shell plate width and thickness, welding process, power supply, consumables, and required automation configuration before ordering.
Also confirm which machine modules are included, whether the selected model suits a small tank or a tank larger than 30 m, and what commissioning, installation guidance, welding-procedure qualification support, training, documentation, and overseas service are available for the specific project.
