Welding Safety, Equipment, Tips & Techniques : Handling Gas Cylinders Safely When Welding

We are living in a world where everything is constantly changing. Science, technology, and medicine are constantly advancing, and the internet has changed the way society shops, communicates, and even educates their youth. There are even incredible advances in industries that are typically very opposed to change. The woodworking tool industry is one such industry.

Recent advances in cutting material has revolutionized the way this industry now builds their tools. At one time a saw shop had to spend a great deal of time, money and resources making frequent stops in production to sharpen and re-tip their saw blades, but a new material for woodworking tools tremendously helps to reduce this down-time. Cermet and Cermet II are advanced grades of Carbide that are more wear resistant, more resistant to breakage, allow tools to work at faster cutting speeds, and stay cool, even at high temperatures. The Cermet material has undergone many changes and many advances to adapt it into woodworking and tooling applications.

Cermets have been proven for decades in metal machining. Cermets were tried in saws about ten years ago and did not work well because no one could keep the tips on. Carbide Processors pioneered new brazing techniques and with their hardwork and U.S. patent 6,322,871 were finally able to apply Cermet technology to woodworking and saw tipping. The Cermets are composed entirely of TiC (Titanium Carbide) and TiN (Titanium Nitride). Tungsten carbides usually have (TiC and TiN) coatings to improve tool life and resist built-up edge. After this thin coating wears away then the insert’s usefulness ends. A cermet is not coated instead it is solid coating material. Since a cermet is a solid composition of (TiC) and/or (TiN), wear is much more gradual – thus the advantage of having a solid substrate. Although the US Patent Office accepts this as a ceramic it is best here to consider it as an intermediate grade between tungsten carbide and pure ceramics. It has a lot of the good qualities of true ceramics as well as an acceptable transverse rupture strength of over 200,000 psi.

Cermets are one of the best kept secrets in the cutting tool industry. They provide the user with increased productivity and profitability through higher cutting speeds and extended tool life. Cermets bridge the gap between ceramics and carbides with speeds ranging from (300 -1200 s.f.m.). They also provide excellent chip control with molded or ground chipbreakers. Carbide Processors was an industry leader in using this revolutionary material for cutting tools. They now make their own line of Cermet tipped saw blades [http://www.carbideprocessors.com/longlifead.htm], and can make any custom tool with this highly durable material.

How do you braze weld?

IS there a certain technique to braze welding? do you make the circular pattern like you do when gas welding and fillet welding? somebody help

not really man, just balance ur torch like u were taught. thats critical and the other thing is its not like welding, no “technique” is really required as far as weaving or circular patterns cause it all just flowes together anyways. what u need to watch for is called “tinning” where ur puddle will flow up just a little bit ahead of ur main puddle, it almost sucks ahead a little bit, then its time to add filler rod to that tinning puddle thats how u know u have the right heat in there and weld progression.
braze welding is BS anyways man, i was good at it in school but i dont really have the patients for it for any lenth of time. but thats how u do it. peace..

During the summer months one of the most common problems with air conditioning systems is getting low on freon. This is a problem that normally ends with the air conditioning contractor putting a few pounds of freon in and calling it quits. This is not the correct way to solve the solution, and never a repair that will last forever. By going through the next steps I have provided in this article you can guarantee your air conditioner will work next year.

The way an air conditioning system works is by using a refrigerant (freon) and letting it change its state to take the heat out of the air. This refrigerant is in a sealed system which should never have to be replaced or recharged. When a proper installation of an air conditioner is performed the contractor should put a vacuum on the system to check for any leaks. If there is a leak in the system it needs to be found and repaired. This is where the problem normally comes into effect. during the installation process either someone had a bad braze weld or didn’t put a vacuum pump on and there is a leak.

This leak could go undetected for a few years and by the time the customer notices it there is no more warranty on the product or installation. When another contractor comes in to look for the problem they just fill it up and take the easy money. This charge to fill with freon can range from $350-$675 and after doing that a few times the customer can spend more than the system is worth. Not to mention the damage the low freon will do to your compressor and cause future problems.

The proper thing to do in the case of a loss of freon is very easy, and after the fix you can be sure that you will never lose freon again.

What you need to see the contract rod is put the system into a positive pressure using nitrogen. By putting that much pressure in the system you will be able to hear the nitrogen leak and repair the problem. If the problem is in the outside or inside coils you need to have them replaced. Hopefully the leak was in one of the original welds and can just be touched up. After the repair there needs to be a vacuum put on the system. By bringing the system to a negative pressure you remove all of the noncondensables and any moisture in the system. Let this vacuum sit for an hour and see if there is any loss. If not recharge to factory standards and you air conditioning system will work well for a long time.
