What does STT stand for in welding terminology?

• A. Standard Transfer Technique
• B. Surface Tension Transfer
• C. Solid Transfer Technology
• D. Short Tension Transmission

Answer: (B)

In welding terminology, STT stands for Surface Tension Transfer. This process is a specialized method commonly used in the GMAW (Gas Metal Arc Welding) technique. The significance of Surface Tension Transfer lies in its ability to effectively control droplet transfer, resulting in a stable and consistent arc as well as improved weld quality. The Surface Tension Transfer technique allows for better control of the molten metal, minimizing spatter and producing clean welds. This is particularly beneficial in thin materials, as it enables deeper penetration while reducing the heat input, which can distort or weaken the base metal. This control is accomplished by adjusting the current and voltage to manipulate the behavior of the molten droplets as they transition from the electrode to the workpiece. Other options, while they may sound plausible, do not reflect established terminology in the welding industry. Understanding STT is essential for welders as it influences the technique and equipment they choose for specific welding applications, making it a valuable concept in both practical and theoretical training in welding.
