Rig welding refers to mobile, truck-mounted welding operations that bring all necessary equipment — power generation, welding machines, gas, tools and consumables — directly to a job site. A rig welder is a highly skilled tradesperson capable of working independently in remote, industrial or time-sensitive environments. CPW Contracting’s rig welding services in Vancouver and the Lower Mainland are suited to heavy industrial projects, construction sites, infrastructure work, and facility maintenance requiring rapid, certified on-site response.
