Welding is going strong today just as it did in the days of yesteryear. With economic gestures of cut-backs on a global market, many are fearful of what the future will hold. Even though the world does not appear to be doing business as it was even one year ago, there will always be a need for the welder. What types of welding would be the best to know?
There is always going to be a need for a skilled metal tradesman in our world. The fact remains that some uses of welding will seemingly never be replaced. Looking at the high pressure impact that goes on inside a place like a boiler or a refinery, it is apparent that the need for certified welders will remain as long as man wants his creature comforts.
It is hard to get by without electricity. If your power went out right now as you are reading this article, you would not be to happy and would pay the necessary amount to get it fixed. So with that in mind. Let's take a look at some of the most used welding applications.
First of all but not least of all we have the stick rod principle. This is truly a backbone process in the welding world. Most people that come into the welding field come into it through the stick application. Even with other more sophisticated processes, most of those high tech activities will use stick at some point.
Quite often we see multiple processes in combination. Look at TIG and stick, or MIG and stick together and so no. Stick is used in a wide scope of welding from plate to pipe and beyond. Almost all metal structures all over the globe involve some type of stick welding. High rise apartments, structures in a shipyard including the ships themselves, to the hanging a sign on a post by the side of the road for advertisement. The possibilities go on and on into a vanishing point.
When trying to learn to weld, the first stop on the route will be the stick rod depot where the welder takes into consideration the many ways that the flux coated rod is used. There a numerous amount of ways that this type of welding is used. This covers the many positions as well as the various coatings that are considered. If you were to weld high pressure in an oil refinery and you used the TIG root and hot pass, the final stage of your welding where certain pipe is used would consist of the flux coated fill and cap.
Can a steel structure that will support tons of physical weight, get around using iron in its construction? Is there any other way to accomplish this task? Quite frankly the answer is no. The days of the hot rivet are long gone. There is still the use of bolting but many times that is coupled with welding. Plate welding still pays pretty good. Even in the bolt up process there is the technique known as killing the nut. This is where the nut on the bolt is tack welded to prevent it from backing off the bolt or stud threads. Still need the welder.
In 2008 there was an estimate need of 250,000 to 300,000 extra welders world wide over the next ten years. Has this dropped slightly since then with our economic decline? Probably so but there will still be a need for increase for welding. China is a fast growing place that is implementing rail systems among many other things. Any time there is metal involved, there will be a guy who can weld floating around the job site.
So we have the stick welder and his demand. Next we have to consider the pipe welder. Of all the welding that is done around the globe, pipe welding is thought to pay the best and carry the most clout. A good pipe welder used to be a very respected individual. Today unfortunately, that mindset has changed. What hasn't changed is that ever growing need for that type of skill. A good idea is to progress as far in the quickest amount of time to the top level of whatever welding field you may be interested in.
There has been a recent influence of pipe that is made of plastic or polymer materials rather than metal. Although this is fact, another fact that isn't going to change is that plastic piping can in no way replace irons or stainless materials where critical pressures or corrosives are used within the piping process. Chemical plants or refineries will always use metal more than anything. Hospitals use a great deal of metal. Dairy equipment, lightweight bicycle frames, power plants, etc. Another aspect of the piping field lies beneath the ground in the oil and gas medium.
If you have ever worked on a drilling rig, you know as well as I do that the hard service of that environment terrorizes the metal industry. There is no substitute for cracked welds but to replace them with fresh welds in that environment.
If you have ever worked in a production shop, the need for a MIG pipe welder can be a reality. MIG pipe welding is some of the fastest way there is to weld the pipe root and hot pass before moving on with the stick hot pass and cap. So if you are considering some training in this vast array of some extremely common but very stable forms of welding; by all means don't let the economy keep you from doing it. There is always going to be a demand for these widely used but simple welding procedures.

Dent Repair Methods
Minor dents are perfectly suited for non-intrusive dent repair. Working from the backside of the dent, a trained technician can gently work the metal outward using plastic-tipped punches. When the process is completed the dent completely disappears without the need for body fillers or paint. Such dent repairs are less expensive than traditional bodywork methods. The technicians often perform these repairs in the car owner's driveway or garage, eliminating the inconvenience of dropping off the vehicle and arranging alternative transportation.
If the dent is deeper or has caused permanent distortion of the surrounding metal, the repair will become much more intrusive, time-consuming and expensive. Such dents and damaged areas must be forced back outward by using a hammer and dolly to slowly move the metal back into shape and nearly flush with the surrounding surface. When it is difficult to gain access to the backside of a dent, or when the backside of the dent may be difficult to reach using a dolly, a small hole in the center of a dent is drilled for a bolt to be attached or to a pin welder is used to tack a pin or series of pins to the damaged surface. Using a slide-hammer attached to the bolt or pins, the dent is pulled outward until it is nearly flush with the surrounding surface.
After the dent has been pulled outward, the remainder of the dent repair is performed using plastic or resin body fillers applied in thin layers over the remaining dent until the surface is built up to the level of the surrounding surface. The body filler is sanded down using very coarse and fine sandpapers until the profile is correct and the body filler flows perfectly with the surrounding surface. Finally, the area must be primed and painted to match the rest of the vehicle.

Would this welder plug into a regular 110 volt socket in my garage?
I haven't ever welded a thing in my life. I just really need to do some tack welds and small jobs. I found this welder online but I'm concerned about how much electricity it needs. If it needs more than a 110 plug I'll have to rethink everything.

It can run on any 110 volt 20 amp circuit. Campbell Hausfeld said it is a 70 amp welder. Not much amps, hope you are not doing anything thick, like more than 1/8". A $100 - $200 more and you can get a Hobart welder, one goes 125 amps and another goes 140 amps much better for thickness both 110 volts. You can get a refurbished 140 for about the same price as the Hausfeld. I have run my Hobart handler on a 15 amp circuit before with no problems (you just can't run it for long periods). I have had mine for 20 years now with no problems or repairs with it.
Good luck.
