All types of welding rely on some form of protection to keep the weld puddle from oxidizing. Molten metal has an afinity to oxygen. Some processes use an inert gas ( ie:GTAW GMAW) the G, being Gas, is usually argon,helium, or CO2. SMAW (stick welding) S being Shielded, uses both slag and smoke to protect the molten puddle. Therefore it stands to reason if the wind is strong enough to blow away the smoke or inert gas then oxygen contained in the air can attack and destroy the weld.

∙ 12y agoWhen using a Mig welder the wind will affect the welding process by blowing away the shielding gases resulting is heavy splatter, porosity and even holes in thinner materials.
Arc welders are not a problem in wind unless you are welding a workpiece that required very high temperature pre-heating, then it could rapidly decrease the temperature of the workpiece and possibly cause cracking. A lower pre-heating requirement workpiece should be alright as the constant welding will keep the temperature of the workpiece up, unless you are working in sub-zero or very low temperature winds.

What do wind vane do?
velocity direction indicator like a wind sock
Wind velocity can be represented as a?
Wind speed is measured in m/s or km/h.
Which is an instrument commonly used to measure wind speed?
An anemometer measures wind velocity.
What is call the wind masurment?
The Beaufort scale is an empirical measure for describing wind velocity based mainly on observed sea conditions.
What is the effect on force if the velocity changes from 5 mph to 10 miles per hour?
Velocity does not affect force.
What is high wind velocity can cause porosity in weld?
hardiflex
What has an effect on air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.

What has an effect on earths air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
How does mass effect velocity?
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
What is used to weld the sheets of the tower on a wind turbine?
Because...
What effect does fraction have on the velocity of the ball?
Do you mean "What effect does friction have on the velocity of the ball?"
What is used to weld the sheets of a wind turbine tower?
welding robot
Why is it important for airplane pilots to know wind velocity and not just wind speed during a flight?
Wind velocity is vector quantity. direction is also important.
What is a sentence for velocity?
The velocity of the wind caused my hair to stand on end.
What is the swiftness of wind called?
It's the wind speed, or, if the direction is included, the wind velocity.
