AHSS Weld Performance Study – Autobody Structural Components

Sep 30, 2024

This project establishes suitable welding parameters for AHSS material iterations (DP600, DP780, DP800, DP980 and HSLA350). Material section thicknesses ranged from 1.0mm to 3.4mm. Five fusion welding processes (GMAW-Pulse/AC, GMAWPulse/DC, Laser-GMAW, Laser, and...

High-Strength Steel Weldability DOE Test Method Correlation

Sep 30, 2024

The objective of developing standard test methods was to eliminate the need for repeat testing of a material with three different test methods (Chrysler’s, Ford’s, and GM’s) to qualify a sheet steel grade. However, to obtain acceptance of the A/SP test methods as...

Operating Procedures for Conducting the A/SP DOE of Coated Steels

Sep 30, 2024

This program is targeted at generating information which will allow subsequent evaluations of tip dressing schedules, stepper schedules, weldgun arm rigidity, machine age, etc. As such, a secondary objective is to establish the procedures that will allow for proper...
