Use the same procedure to create a plug weld or a slot weld. The only difference is that a plug weld’s shape is defined by a diameter, and a slot weld’s shape is defined by a diameter and a length.
Plug welds are a round weld that is made inside of an existing hole most commonly in one piece of metal, welding that piece to another member. The plug weld symbol is a rectangle with a diameter symbol placed to the left of the symbol as well as the number associated with that diameter.
Beside this, How big should a plug weld be?
The minimum diameter of the hole for the plug shall be no less than the thickness of the part containing it plus 5/16(8mm) preferably rounded to the next greater odd 1/16″. The maximum width shall equal the minimum width plus 1/8″(3mm) or 2-1/4 times the thickness of the member,which ever is greater.
Likewise, What is plug and slot weld?
Plug welds and slot welds are used to join overlapping members, one of which has holes (round for plug welds, elongated for slot welds) in it. Weld metal is deposited in the holes and penetrates and fuses with the base metal of the two members to form the joint.
Also, How big is a spot weld?
The two materials being welded together are known as the workpieces and must conduct electricity. The width of the workpieces is limited by the throat length of the welding apparatus and ranges typically from 5 to 50 inches (13 to 130 cm). Workpiece thickness can range from 0.008 to 1.25 inches (0.20 to 32 mm).
What is plug weld joint?
Plug welds are a round weld that is made inside of an existing hole most commonly in one piece of metal, welding that piece to another member. … Some plug welds may include a countersink of the hole of the plug weld.

What is the tip diameter in spot welding?
Welding tip diameter is very important. The TITE-SPOT Pliers has the welding tips sharpened to 3/16″ diameter when new. The tips can be allowed to fatten to 1/4″ diameter before they need to be sharpened. Welding tips have a flat face when new.
Are spot welds strong?
Spot welding is useful in many circumstances, although there are certain limitations. It can create only localized joins, which may not be particularly strong. The strength of a spot weld depends on the force and temperature that has been applied and on the cleanliness of the electrodes and metal.
How far apart should spot welds be?
Spot Weld Spacing Distance between two spot welds depends on the sheet thickness and material. Narrow spacing between two consecutive spot welds should be avoided to achieve good weld strength. It is recommended that distance between two spot welds should be a minimum of 10 times the material thickness.
Is spot welding hard?
In contrast, spot welding can be difficult with metals such as aluminum and galvanized steel since both require higher levels of electrical current for weld formation. However, even the best material can be difficult to weld if it is not of the appropriate thickness.
How strong is spot welding?
This weld has a shear strength of 1100 lbs. (499.5kg) less than the fully penetrated weld. For a full penetrating spot weld on a given plate thickness, the area of the interface will depend to a large extent on the shielding gas and the arc voltage.
What is the correct sequence for spot welding?
Spot welding involves three stages; the first of which involves the electrodes being brought to the surface of the metal and applying a slight amount of pressure. The current from the electrodes is then applied briefly after which the current is removed but the electrodes remain in place for the material to cool.
What type of welding is strongest?

What are plug welds used for?
INTRODUCTION TO PLUG WELDING Plug welding is primarily used to refill damaged holes on aerospace components such as fan and exit cases. Our process allows aerospace companies to salvage these components by fixing each individual hole, instead of scrapping the entire assembly.
What is the easiest metal to weld?
Steel
