What is the correct travel speed in welding?

What is the correct travel speed in welding?

3 to 6 inches per minute
The suggested travel speed for SMAW is 3 to 6 inches per minute (ipm) / 75 to 150 mm/min. SMAW of Ni-base alloys is not well suited for out-of-position welding and generally only feasible with 0.093 in (2.4 mm) and 0.125 in (3.2 mm) diameter electrodes.

How does travel speed affect the weld?

In most cases, weld penetration into a base material is increased when the travel speed of a weld is increased, and vice versa. At slower travel speeds, the arc is directly above the center of the molten weld pool.

What are the 5 parameter’s of welding?

The four important parameters are the welding current, wire electrode extension, welding voltage and arc travel speed. These parameters will affect the weld characteristics to a great extent. Because these factors can be varied over a large range, they are considered the primary adjustments in any welding operation.

What is ARC travel speed?

ARC TRAVEL SPEED The arc travel speed is the linear rate that the arc moves along the workpiece. This parameter is usually expressed as inches or meters per minute.

What is the importance of correct travel speed?

CORRECTTRAVEL SPEED When your speed is too fast your pool does not last long enough, impurities an gas locked in. The bead in narrow and ripples pointed. When speed is too slow the metal piles up, the bead is high and wide with a rather straight ripple.

What is travel angle in welding?

Proper work angle, travel angle and movement Work angle is “the relationship between the axis of the electrode to the welders work piece”. Travel angle refers to employing either a push angle (pointing in the direction of travel) or a drag angle, when the electrode is pointed opposite of travel.

What are the 7 hazards of welding?

Welding Hazards and Safety Risks

• Exposure to Fumes and Gases. Overexposure to welding fumes and gases can cause severe health problems like respiratory illnesses, cancer, and impaired speech and movement.
• Physical Hazards.
• Electric Shock.
• Fire and Explosion.

What is angle of travel?

Is the angle between the electrode and the weld in a plane that is parallel to the direction of travel.

What is the difference between work angle and travel angle?

Work angle is “the relationship between the axis of the electrode to the welders work piece”. Travel angle refers to employing either a push angle (pointing in the direction of travel) or a drag angle, when the electrode is pointed opposite of travel.

What are the top 10 safety rules when welding?

10 Arc Welding Safety Tips

• Tip #1 – Read the owner’s manual, warning labels and relevant codes.
• Tip #2 – Avoid electric shock.
• Tip #3 – Shield eyes and skin from UV light.
• Tip #4 – Avoid burns.
• Tip #5 – Maintain your equipment.
• Tip #6 – Avoid breathing fumes.
• Tip #7 – Protect your eyes and ears.
• Tip #8 – Wear the right gear.

What is travel angle welding?

Travel angle is defined as the angle relative to the gun in a perpendicular position. Normal welding conditions in all positions call for a travel angle of 5 to 15 degrees. Travel angles beyond 20 to 25 degrees can lead to more spatter, less penetration and general arc instability.

What is travel speed in welding?

Travel Speed. In most cases, weld penetration into a base material is increased when the travel speed of a weld is increased, and vice versa. At slower travel speeds, the arc is directly above the center of the molten weld pool.

How do you calculate the travel speed of a fillet weld?

Of course, the travel speed for a one-pass 3/8 in fillet weld at a 12 lb/hr deposition rate would be 8.31 ipm as calculated below: Travel Speed = (deposition rate) × (# of passes)/5 × (weight of weld metal {lb./ft}) = (12) × (1)/5 × (0.2887) = 8.31 ipm

How do you calculate wire feed speed in welding?

Wire-Feed Speed Calculation. Wire-feed Speed = (deposition rate)/5 × (weight of wire per foot {lb/ft}) = (12)/5 × (0.0054) = 444.4 ipm. Of course, the travel speed for a one-pass 3/8 in fillet weld at a 12 lb/hr deposition rate would be 8.31 ipm as calculated below: Travel Speed = (deposition rate) × (# of passes)/5 ×

Which welds have increased penetration into the base metal?

Weld 30 through Weld 34 had increased travel speeds and consequently increased penetration into the base metal. The weld data for these welds is shown in Table 1. Figure 1: Cross Sectional View of Welds 30-34. Red outline better displays the penetration profile. Slower travel speeds result in a solidification pattern that is circular or oval.
