The correct answer is from left to right.

In fore-hand welding, the weld is made by pushing the welding rod forward, in the direction of the weld, from left to right. This is the most common and preferred direction for fore-hand welding because:

- It allows for better visibility of the weld pool
- It enables easier control of the weld pool
- It produces a more consistent and higher-quality weld

Welding from left to right also helps to:
- Prevent porosity and slag inclusions.
- Reduce the risk of weld defects.
- Improve the overall appearance of the weld.

The other options are incorrect because:
- From right to left: This direction is not typical for fore-hand welding and may lead to poor visibility and control.
- First from left to right and then from right to left: This is not a standard practice in fore-hand welding.
- Either from left to right or from right to left: While it is possible to weld in either direction, left to right is the preferred and most common direction for fore-hand welding.

The direction of welding may vary depending on the specific welding process, material, and joint configuration.

However, for fore-hand welding, left to right is the most commonly used and recommended direction.

Left ward or fore hand welding weld is made from right to left. Torch makes an angle of 60 - 70 degrees.

Welding rod makes an angle 30-40 degrees.
