What is longitudinal fillet weld?
When the applied force is parallel to the length of the weld is called longitudinal fillet weld. When the applied force is perpendicular to the length of the weld is called transverse fillet weld.
What is a transverse fillet weld?
A transverse fillet weld is one that is perpendicular to the force applied as seen in the image below. Because the load is perpendicular to the weld it is considered a tensile load.
What are the two types of fillet weld?
There are two main types of fillet weld: transverse fillet weld and parallel fillet weld.
What are the three types of weld throat and what is its difference?
– Actual throat – The shortest distance between the weld root and the face of a fillet weld. – Theoretical throat – The distance from the beginning of the joint root perpendicular to the hypotenuse of the largest right triangle that can be inscribed within the cross section of a fillet weld.
What are the different types of welds?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW).
What is side fillet?
Fillet welds are one of the most common weld types in the industry. This weld is used when the joint has two members coming together to form an intersection of commonly 90 degrees. Fillet welds may have a size associated with them. This size is called out on the left side of the symbol before the vertical side.
What is the difference between a welding symbol and a weld symbol?
There has been always confusion between a welding symbol and weld symbol. A Welding symbol is different from a weld symbol; which is a graphic character connected to the reference line of a welded symbol specifying the joint geometry. So basically, the weld symbol is a part of the welding symbol.
What is the difference in welders?
The difference between the two is the way the arc is used. MIG (metal inert gas) welding uses a feed wire that constantly moves through the gun to create the spark, then melts to form the weld. TIG (tungsten inert gas) welding uses long rods to fuse two metals directly together.
What is the difference between longitudinal and transverse cracks?
Depending on the orientation of the crack in the weld, it can be classified as longitudinal or transverse. Longitudinal when the direction is parallel to the weld and transverse when the direction is across the weld or at 90 degrees.
What are the principal forms of distortion for Butt and fillet welds?
The principal features of the more common forms of distortion for butt and fillet welds are shown below: Contraction of the weld area on cooling results in both transverse and longitudinal shrinkage. Non-uniform contraction (through thickness) produces angular distortion in addition to longitudinal and transverse shrinkage.
What are the types of defects in the welding process?
Porosity and other cavities such as wormholes and blowholes are caused by entrapment of gases in the weldment. These are classified as internal and volumetric defects. Linear – A line of gas pores substantially parallel to the axis of the weld Surface pores – A gas pore/s which breaks the surface of the weld, uniformly distributed porosity
What are the causes of under fill in welding?
Generally caused by welding current that is too high, travel speed that is too high or an incorrect operator technique. Under-fill is a longitudinal continuous or intermittent area in the surface of a weld that is below the adjacent surface of the parent metal due to insufficient deposition of weld metal.
