A T-joint consists of two plates welded at 90° to each other in the form of a 'T'. Commonly used in the structural industry, T-joints generally use fillet or groove type welds on each side of the vertical plate, these welds can be 'part' or 'full' penetration welds, each presenting their own challenges.
What are the types of welding?
TIG welded joins are typically stronger than those produced by MIG welding. This is because the narrow, focused arc created by TIG welders offers better penetration of the metal. In addition, the TIG weld beads, when applied correctly, contain few holes and other defects that can weaken the weld.
What is the weakest weld?
MIG (GMAW)
Gas metal arc welding, also called metal inert gas (MIG) welding, is a high-speed process that's fairly easy to learn. This and the fact that you can make clean and strong welds is why it is the most common type of welding used in manufacturing.

It's an average of five times faster than electrical arc methods and includes four material transfer options: spray, pulsed spray, globular and short circuiting.
How long is a duty cycle?
Shielded Metal Arc Welding (SMAW)
This form of welding is more commonly known as stick welding and is the most basic of the different types of welding to use. The welder uses a stick with an electric current flowing through to create an arc between the two metals to join them.
What is the T joint?
What's the easiest type of welding to learn? MIG welding is generally the easiest type of welding for a beginner to learn. MIG welders use a feed wire that runs through the machine at a preselected speed. This makes the process relatively fast and produces consistent welds.
Is MIG or TIG stronger?
The workpiece and the weld are perpendicular or almost perpendicular in this welding position. 3F is the vertical fillet position, and 3G is the vertical groove. One issue when performing this weld is the molten metal flowing downward and accumulating. In the Vertical position welding the welds axis is almost vertical.

How are joints classified?
With these facts in hand, it is plausible to conclude that most welding, if done correctly and with the proper weld sizes and lengths, is usually stronger than the base metal. Yes, welding weakens steel, particularly in the HAZ (heat-affected zone) if done at high temperatures.
What metals Cannot be welded?
Aluminum. The first impression of aluminum is that since it is pliable and easily manipulated, it should be easy to weld. In reality, it is considered to be the most difficult metal to weld since it is an alloy and therefore mixed with other metals. Some have even called welding with aluminum a “nightmare.”
Why do weld joints fail?
Stainless steel has a much higher thermal conductivity than other metals, which requires more heat input to weld correctly. This makes it more difficult to control the welding process and can cause distortion and warping of the material.

MIG (metal inert gas) welding is an excellent choice for beginning welders. This easy-to-handle machine is usually spool-fed to create professional-looking joints on both thick and thin metals. MIG welding requires separate shielding gas but doesn't require chipping and cleaning slag as the stick welding process can.
Can you weld on aluminum?
For example, a signal (10101010) has 50% duty cycle, because the pulse remains high for 1/2 of the period or low for 1/2 of the period. Similarly, for pulse (10001000) the duty cycle will be 25% because the pulse remains high only for 1/4 of the period and remains low for 3/4 of the period.
Is weld stronger than steel?
A 100% duty cycle simply means the compressor will deliver a consistent CFM and PSI the entire time the compressor is in use, which is different than being able to run continuously. A piston-type compressor eventually needs to stop and cool down even if they are rated at 100% duty cycle.
What is the most difficult metal to weld?
How is duty cycle calculated? If a machine has a duty cycle of 25% it means it can run at the given amperage for 2,5 minutes followed by 7,5 minutes cool down. And if the machine has an 80% duty cycle it can run in 8 minutes followed by 2 minutes cool down.
