How do you explain welding defects and explain its testing?
Defects can be varied and classified as critical or non critical. Porosity (bubbles) in the weld are usually acceptable to a certain degree. Slag inclusions, undercut, and cracks are usually non acceptable. Some porosity, cracks, and slag inclusions are visible and may not need further inspection to require their removal. Small defects such as these can be verified by Liquid Penetrant Testing (Dye check). Slag inclusions and cracks just below the surface can be discovered by Magnetic Particle Inspection. Deeper defects can be checked thru X-raying.
What are the welding defects in sheet metal?
Porosity is the most common weld defect. For beginners don't rule out lack of penetration and non-compatible welding rod or filler wire. It all depends on how the weld failed if it has. Proper prep and preheat is required in many types of welding. So a little more detailed question can help me give you a more detailed answer. Trapped slag is also a common problem. It creates a void in the weld. Although porosity is the most common defect some porosity doesn't necessarily affect the weld strength.
What can slag be used for?
waste slag from blast furnaces is used for road surfacing.
Did Michel Osborn weld the slag hammer?
Yes that Cracker welded the slag Hammer>
What is slag optimization?
Slag purifies and removes unwanted materials from metal. Optimization is the application of foams and other agents to enable a higher quality and stabilized slag to produce a higher quality metal product. Efforts are made to achieve an optimum slag viscosity by the fixation of basicity and temperature.
How do you prevent the occurrence of slag inclusion and undercut?
The following techniques can be used to prevent slag inclusions: Use welding techniques to produce smooth weld beads and adequate inter-run fusion to avoid forming pockets to trap the slag. Use the correct current and travel speed to avoid undercutting the sidewall which will make the slag difficult to remove.
How would you avoid accurence porosity or slag on weld?
Correct current,travel speed, electrode angle, arc length
What are the various procedures for visual examination of the welds for cracks porosity and slag inclusions?
ooo
What are the functions of a slag in welding?
Slag in welding acts as a protective layer on the weld pool, shielding it from atmospheric contamination. It also helps to facilitate the removal of impurities and solidification of the weld by providing a controlled cooling rate. Additionally, slag improves the appearance and quality of the final weld by reducing defects such as porosity and cracking.

How do you avoid slag inclusion?
To avoid slag inclusion in welding, make sure to properly clean the joint and remove any contaminants like rust, oil, or paint. Use the correct welding technique and parameters to ensure good fusion between the base metals. Additionally, selecting the appropriate welding consumables and maintaining a consistent travel speed can help prevent slag inclusion.
How does arc length affect a weld?
Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.
