Do you need a degree for under water welding?
not a college degree but if you do it could help alot
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
What You Receive From A Welding Education?
When you attend welding school you will gain a wealth of knowledge. Welding education is more than learning how to turn a welder on, it is an in depth study of metals and alloys. All metals and alloys are not welded in the same manner. Because of the different types of properties each have they must be welded accordingly. When you get your welding education you will learn the difference between MIG, TIG, Flux Core and Heli Arc welding. You will gain a working understanding of how each metal is used in the construction industry and how to secure them. You will also learn about the different types of welding equipment. If you further your education you may advance to become a welding inspector. Welding is such a crucial aspect to any construction project that inspectors are highly trained and well paid positions. Welding is the basis for most types of construction. Buildings, ships and even roads all have a metal structure to them. Welding is one of the few careers that will not disappear in the new technological age. You will find there are many welding positions in the shipbuilding industry, car industry and , of course, construction industry. There are many private sector jobs that require welding and weld shops are found everywhere in the country. You may also further your education to include specialty welding. There is always a need for under water welders or welders that can work on specialty alloys. Under water welders will be required to have a scuba diving certification prior to receiving a welding cert. When you are ready to graduate you will be given the certification tests. These tests are for working with different metals and welding in different positions. Each certification that you pass will enhance your employment opportunities. While being certified is not required in many welding positions, it is a bonus for higher paying jobs in the workforce. A welding education can take anywhere from 18 months to 4 years to acquire. The length of your schooling will depend on how advanced you wish to go. To make welding inspector you will need a 4 year degree. Specialty welding may add a year to your education. In general, a welder can be educated and certified in less than 2 years.
What is porosity on metal welding?
Weld porosity is gas formations that did not escape prior to the weld solidification. These gases can be formed from water (which breaks down to hydrogen and oxygen atoms), oil, paint, rust or many other contaminants. The welding contamination can be on your welding materials as well as on the base metal (damp welding electrodes, etc.).
What is the process of underwater welding?
Underwater welding uses a special flux around the welding rod which produces gasses which form a bubble around the end of the rod ,excluding the water. It is difficult and never as strong, lacking penetration. It is only used when absolutly necessary.
Why do under water welders die so often?
There's only been one incident involving an actual death during the process of underwater welding, which happened in 1943 when a student was wet welding. The potential danger from electric current during underwater welding is extremely low because the welder-diver is grounded. It's also direct current (DC), not alternating current (AC), so it's focused at the weld site. Other dangers to underwater welders (commercial divers) are more prevalent, including decompression sickness and drowning. I outline these dangers in my article: waterwelders.com/zap-bang-pop-hazards-safety-measures-of-underwater-welding/
What is h(-3)?
H-O-H is the symbol formula of WATER. H2O
What are the duties of an underwater welder?
sub-mersible welding machine using reverse polaity. miller welding company as well as Lincoln specialize and sell welding equipment. for more info contact the Ocean Corp in Houston tx.
What is water down under?
Water down under is ground water.
What kind of welding pays the most salary?
Several types of welding jobs offer high pay rates due to their specialized nature and demand for skilled professionals. Among these, underwater welding stands out as a top-paying option. This challenging field involves welding in marine environments and requires expertise in both welding techniques and diving. Another area is pipeline welding, where welders work on constructing and maintaining critical pipelines for industries like oil and gas. Additionally, aerospace welding offers high-paying opportunities, as it involves joining metals for aircraft and spacecraft construction, requiring precision and adherence to stringent quality standards.
In welding what is used as a cleaning agent to dissolve oxides and cleanse metals for welding soldering and brazing?
It is generally called a flux or cleansing agent. Sometimes contained in electrode coatings and found in powdered form to use in the Oxy-fuel welding process. Primary ingredient is Borax ( yah same as in some hand cleaners). Often mixed with water to form a paste that can be applied by a brush to both the welding/brazing rod and also the base metal.
How does current flow during welding?
Think of electricity as water in a pipe. The larger the pipe the more water can flow thru. That is current = volume = amperage = amount of heat. Voltage can be compared to pressure in a pipe. That is drive/force. Most welding machines allow you to control the amperage but not the voltage.
