Testing the Strength and Integrity of Welding Studs Attached to Sheet Metal

The Mountz Weld Stud Test Tool is designed for use during the production of sheet metal products to test the strength and integrity of welds used to attach threaded studs to the sheet metal.

Application Story # 1
A company that manufacturers popcorn machines, conveyor ovens, and toasters in Missouri wanted capability to test welds on equipment before completion of the assembly process. The problem occurring was that the welding studs were breaking out in the field costing the company time and money, which ultimately affected their bottom line. This company strives on their quality and knew there had to be a solution. When evaluating the problem the breaking point of the studs was unknown. Also, there are 4 different size studs that are welded into place, all of which needed to have different weld specifications.

The solution was the implementation of the Mountz WSTT (Weld Stud Test Tool) and TorqueLab torque tester. With this equipment they were able to develop specifications to be used with each of the different size studs they are welding. Once this was accomplished and proven to be a successful solution to eliminate weld studs breaking out in the field, they color coded the tools, placed on a cart and used on all their production lines throughout the facility.

Their Mountz Weld Stud Test Tools are sent to the quality lab once per week to be verified on the Mountz torque analyzer.

Application Story # 2
Another company taking advantage of the Mountz Weld Stud Tools to test the strength and integrity of welding studs was a manufacturer of metal enclosures. This company needed a verification process to test all welds on the metal enclosures being manufactured. Their current system was to test the welds using a metal chip approximately 4"x4" and doing a test weld. They were using various metal thickness so several chips were being used at one time depending on the enclosures thickness. This was becoming quite costly in materials and time.

The solution was to set up test parameters for all metal thicknesses used in the manufacturing of their metal enclosures using the WSTT (Weld Stud Test Tool). Once these parameters are developed, the account will know the type of welds needed for each metal thickness and the welder can then check each weld on the on the enclosures being manufactured using the WSTT. This will give the account instant verification that the weld is good. It also will save them money by not having to buy the metal chips they were using to test a weld before they started manufacturing the enclosure.

Get Easy Test Results
A simple way to test the shear torque of weld studs. Apply a straight pull of the WSTT wrench (no side load). When the wrench breaks-over and the weld stud is still attached then it passed. If the weld stud breaks off - then it failed.
