weldingLDJ Manufacturing’s D1.1 certified welders are prepared with a full arsenal of options which include Pulse, Spot, Short-Arc and TIG welding. Our Panasonic Perform Arc robotic welding system offers the precision repeatability of computerized welding. This specialized robot can weld from two sides in tandem while maintaining a repeatability factor of +/- .004 inches.

Recently, LDJ completed a large weld job for a world-renowned customer. To our disappointment, the order was quarantined when one of the customer's painters noted a missing weld. Upon further investigation, it was discovered that the weld was in fact there, but could not be detected beneath the paint due to the precision and smoothness of the welded steel.
