Which types of metal transfer do NOT put much heat into the work and can be used in all positions?

The chosen answer highlights the correct understanding of metal transfer methods in welding. Short circuiting transfer is characterized by low heat input into the workpiece, making it suitable for vertical and overhead positions, as it reduces the likelihood of burn-through or excessive heat affecting the material. Additionally, pulsed spray transfer operates at lower heat inputs by controlling the transfer of metal droplets, allowing for a focused arc that is advantageous in various welding positions.

Both of these transfer types are favorable for applications where heat management is critical, particularly in thinner materials or in situations where distortion from heat needs to be minimized. Their ability to operate in all positions makes them versatile options for welders, accommodating various project requirements and techniques.

In contrast, methods like globular transfer and spray transfer tend to introduce higher heat inputs, which may not be suitable for all positions or for more delicate work. Understanding these distinctions is crucial for selecting the appropriate welding technique based on the material type, thickness, and joint configuration.
