Oxy–acetylene technique — travel direction in forehand (leftward) welding In gas welding practice, forehand welding (also known as leftward welding) is characterized by the torch leading the filler. In which travel direction is the weld typically made?

Introduction / Context:Oxy–acetylene welding uses distinct techniques: forehand (leftward) and backhand (rightward). Knowing the correct travel direction improves heat distribution, puddle control, and joint quality, especially on thin sheets.

Given Data / Assumptions:

• Forehand (leftward) technique is specified.
• Operator maintains a neutral flame unless otherwise required.
• Filler rod is fed ahead of the molten pool with the torch leading.

Concept / Approach:In forehand welding, the torch points in the direction of travel, preheating the joint ahead of the puddle. The conventional description is left-to-right travel (hence leftward), ideal for thin sections due to broader preheating and lower risk of burn-through. Backhand welding is the reverse, commonly used for thicker sections.

Step-by-Step Solution:

Verification / Alternative check:Welding training manuals define forehand as leftward travel with specified torch and rod angles conducive to sheet work.

Why Other Options Are Wrong:

• Right to left: that is backhand (rightward) welding.
• Both directions or circular weave only: not specific to forehand definition.

Common Pitfalls:Confusing torch angle and rod angle; mixing up forehand/backhand names versus the actual movement on the workpiece.

Final Answer:
