7.6 Practical recommendations MIG / MAG welding.
Butt welds in the flat position must be carried out using "push" for thin components and
technology "pull" for items thicker. Butt welds in vertical position for thin elements should be done
from top to bottom. Fillet welds in position nabocznej should be carried out using "push", but with an
additional tilt the torch in a plane perpendicular to the direction of welding. In the case of filling the
wide grooves in the flat position
or the vertical end of the handle must be performed
lateral swinging movements. During welding, the welding gun should be conducted at a right angle
relative to the parts to be welded -If high helix angle may result in sucking air into the liquid metal
angle (from the vertical holder should be ≤ 10 °). Long arc welding reduces the depth of penetration -
the seam is wide and flat, and is accompanied by increased weld spatter.
Short arc welding (with the same current density) increase the depth of penetration - the weld is narrower,
and the spatter material becomes smaller. The welding speed is a parameter output at a given current
intensity and arc voltage, and maintaining the correct shape of the weld bead, and when the welding speed
may even be slightly changed, change the current or the arc voltage. The increase welding speed makes the
weld is narrower and decreases the depth of penetration, and with further increase in the face of flooding
occur. The largest welding speed, without undercuts, can be obtained by increasing the stick electrodes and
the inclination of the object up and down or tilt in the direction of the welding torch. Small welding speeds
cause that increases the depth of penetration, face width and height of the riser.
Excessive lengthening or shortening the arc can
cause unstable arc glow and poor weld quality.
L1, L2 - arc length
The depth of penetration is also significantly impact
the direction of welding - carrying the torch.
H1, H2 - the depth of penetration
Due to the nature of the shielding gas and the electrical parameters of the welding process (voltage
and current) There are three ways to change the physical state of the metal in the arc welding:
