Yes. However, there are paints designed to be compatible with welding as they are designed to protect the surface of the plate from corrosion while in storage.
In every code or specification, it is specifically stated that welding should be done on clean metal. Welding over paint is discouraged.

What factor mainly defect welding depth in electron beam welding?
Many factors affect welding depth and penetration, including voltage, material being welded, current, distance from electron gun, vacuum, cleanliness, filament current, and focus.
How does length of gas nozzle effect mig welding?
The legth of the gas nozzle can affect the MIG welding process because it modifies the "electrode extension" or so called stickout. The longer the nozzle the longer electrode extension needed to keep the arc away from it thus the value od the welding current and arc voltage changes. These changes will have a great effect on the weld.
What is crown mean in welding?
In welding, the term "crown" refers to the highest point or the raised surface of a weld bead. It is an important aspect of weld appearance and quality, as a well-defined crown indicates proper fusion and shape. The crown can affect the strength and performance of the weld joint, so it is crucial for welders to achieve the correct crown profile during the welding process.
What is the ambient temperature of stud welding?
The ambient temperature for stud welding typically ranges from 32°F to 104°F (0°C to 40°C). Operating within this range ensures optimal performance and quality of the welds. Extreme temperatures outside this range may affect the welding process and the integrity of the weld. It's important to monitor conditions for consistent results.
Can welding fluxes affect the penetration and contour of the weld bead?
Yes, welding fluxes can significantly affect the penetration and contour of the weld bead. Fluxes help stabilize the arc and protect the molten metal from oxidation, which can enhance penetration. Additionally, different types of fluxes can influence the fluidity of the weld pool, affecting the bead's shape and contour. Proper selection and application of flux are crucial for achieving desired weld characteristics.
Does lacquer affect cello tone?
Yes, if there is too much lacquer used on a cello then it would produce a more dull sound. Less lacquer means a brighter sound. Some people argue that the type of lacquer can change the sound, but only in a very, very minute way.
What do the numbers on a welding rod mean and how do they affect the welding process?
The numbers on a welding rod indicate its characteristics, such as the type of metal it is made of and its tensile strength. These numbers affect the welding process by determining the suitability of the rod for specific welding tasks, such as the type of metal being welded and the welding technique being used. Choosing the right welding rod based on these numbers is crucial for achieving a strong and durable weld.
How can you tell if something is cover with lacquer or varnish?
Shellac and lacquer are both fairly easy to identify because they will redissolve in their original solvents. If alcohol (solvent alcohol from the hardware store, not rubbing alcohol) dissolves it then it's shellac. If lacquer thinner softens it, then it's lacquer. (lacquer thinner will also dissolve shellac, but alcohol will not immediately soften lacquer, so do the alcohol check first.) If neither alcohol nor lacquer thinner immediately affect it, then it's probably varnish.* http://ths.gardenweb.com/forums/load/wood/msg0822004022412.html
How does the process of melting magnesium affect its properties and applications?
When magnesium is melted, its properties change because it becomes a liquid instead of a solid. This can make it easier to shape and mold into different forms. The melted magnesium can be used in applications such as casting, welding, and as a coating for other materials.
What affects the film coating of drugs?
The temperature, air flow, spray rate, and atomisation pressure affect the film coating of drugs.
Can welding mess up a guy's balls and his chances of having kids?
Only if you are zapping them with the welding rod. Welding either Arc, or wire feed does not generate any sort of radiation or anything else that would affect you.
What is the difference between lacquer and paint thinner?
Lacquer thinner evaporates quicker. It is cleaner or leaves less of a film than paint thinner. Lacquer thinner will thin most solvent based paint but paint thinner shouldn't be used to thin Lacquer. Lacquer dries from the surface painted out and enammal dries from the surface of the paint down to the surface painted. Using the wrong thinner affects how the paint dries and may affect the final finish.
What affect does welding polarity have on where heat is directed?
In DC welding, electrode positive (DCEP) produces more heat at the workpiece, leading to deeper penetration and faster welding speeds. In contrast, electrode negative (DCEN) focuses more heat on the electrode, resulting in shallower penetration and slower welding speeds. AC welding alternates between these effects with each cycle.
What factor mainly defect welding depth in electron beam welding?
Many factors affect welding depth and penetration, including voltage, material being welded, current, distance from electron gun, vacuum, cleanliness, filament current, and focus.
What does spatter mean in welding?
Spatter in welding refers to the small droplets of molten metal that are expelled during the welding process. These droplets can land on the surrounding surfaces and create unwanted weld spatter, which can affect the appearance and quality of the weld. Proper welding techniques and equipment settings can help minimize spatter formation.
Does acid rain affect germination of seeds?
Yes, acid rain does affect germination of seeds by mixing in with the soil and damaging the seed coating.
What are the advantages and disadvantages of film coating?
Film coating is less time consuming than compression coating as less time is needed to dry the coat. As the coating is thin, its presence will not affect the tablet's weight that much. This method can also be used to create sustained release formulations. However, film coating is quite expensive due to the high cost of the coating material. The quality of the film also has to be monitored to ensure that they are continuous and uniformly thick.
