Summarize the advantages and disadvantages of the forehand technique.
What will be an ideal response?
The advantages of using the forehand welding technique are:
*Joint visibility-you can easily see the joint where the bead will be deposited
*Electrode extension-the contact tube tip is easier to see making it easier to maintain a constant extension length
*Less weld penetration-it is easier to weld on thin sheet metal without melting through
*Out-of-position welds-this technique works well on vertical up and overhead joints for better control of the weld pool
The disadvantages of using the forehand welding technique are:
*Weld thickness-thinner welds because less weld reinforcement is applied to the weld joint
*Welding speed-because less weld metal is being applied, the rate of travel along the joint can be faster which may make it harder to create a uniform weld
*Slag inclusions-some spattered slag can be thrown in front of the weld bead and be trapped or included in the weld resulting in a weld defect
*Spatter-depending on the electrode, the amount of spatter may be slightly increased with the forehand technique
