By making connections and then apply to welding rods to study the penetration depth of the welding from a comparison of the experimental results found in t-joints, which are considered the islet there welds the difficulties Phil in chueammakkwa per man and quite many such errors. Welds are not absorbed deep into the piece. The salaek difficult to knock out occurred. Heat in large pieces, which requires specialized skills.

Then the connection by connecting to the rods to study the penetration of the weld from the comparison of the experimental. Link to trace the shape of which is welded Phil Catlett more difficult to weld than a butt. And a somewhat more such errors. Welds not penetrate deeply into the workpiece. Slag was knocked out easily. Heat a large specimen. This requires skillful

The welding and the welding smashed to study deep percolation of welding from the comparison, the results showed that Welding seam image t which is considered as a Phil lets the weld has difficulty in welding than to hit.Welds not penetrate deeply into the workpiece. The slag that knocked out difficult. Heat the workpiece. Which requires skill.
