ARGWELD ® TRAILING SHIELDS

Electrode force is one of the critical parameters in obtaining repeatable, reliable resistance spot welds. Improve quality control, ease inspection and allow for regular calibration of resistance welding machines. Incorrect Force Causes: Weld Failures, Reduces fracture toughness of the weld slug and heat-affected zone (HAZ), Increases Reject Rate & Loss of Production. Not Applying The Right Force - Means You Feel The Pressure! Use one of two pioneering electronic force gauges for your quality control. ELECTRONIC FORCE GAUGES FOR RESISTANCE WELDER ELECTRODE FORCE MEASUREMENT KNOW THE FORCE - EASE THE PRESSURE

SHG0001 ( ) Swivel Head Electronic Force Gauge TESTWELD TM

• Hand held portable unit • Very high accuracy (Class III) • Swivel Head Design • Range: 0-2000 kg, 0-20.00 kN, 0-4400 lbs

OD and ID Argweld ® Trailing shields working together allow for a simultaneous top and back purge on a stainless steel vessel.

KR1000 ( ) Resistance Welder Electrode Force Gauge for Robot Welders TESTWELD TM

“A simple yet powerful tool to monitor electrode force in automated welding stations”

• Hands-free auto checking of Electrode Force. • No need to stop robot cells for force checking. • Increased production offsets the cost of Gauge. • Alerts operators to faults and performance variations. • Significantly reduces damage & wear to the equipment. • Keeps force within preset limits and reduces scrap. • Gives early warning of possible equipment deterioration.

Shields are radiused for both internal and external welding of pipes, tanks and vessels. Straight shields are included in the product line for welding flat sheet and plate. Small lightweight shields for manual welding and longer, wider shields for faster welding with automatic systems.
