Application Note Selection [FR]

Heating Steel Cutting Tools for Carbide Removal

Using induction to heat magnetic steel cutting tools for removal of carbide cutting tips. Induction efficiently and precisely heats the client's part in a controlled manner delivering only the required heat.

Brazing, De-brazing Carbide, Steel Plates

A custom-designed special multiple-turn helical coil was built to generate the required heating to heat a carbide and steel plate assembly for a brazing and de-brazing application in the oil and gas industry.

Brazing a Carbide Tip and Magnetic Steel Tube

To braze carbide inserts into magnetic steel tubes, an inconsistent torch process was replaced with induction brazing equipment. In this application, quality rather than speed was the top priority.b

Brazing a Steel and Carbide Assembly

To braze a steel and carbide assembly to create a mining bit for the oil and gas industry, this client replaced their torch process with the repeatable and flameless induction brazing technique.

Brazing, De-Brazing Diamond Carbide Inserts

Heat steel cutting bits with diamond-carbide inserts for brazing and de-brazing; the end products are cutting tools

Brazing a steel and carbide dental assembly

This configuratoin achieved the client's objective. The channel coil - specially designed by THE LAB at Ambrell- was critical to the application's success.

Copper block & carbide; contact assembly

Induction completed the carbide brazing process more rapidly than an oven, delivering heat exactly where it's needed, operating instant on/instant off

Brazing a steel coupler and a steel wire

Induction heating enabled the brazing process to be completed within 30 seconds. The client was using a torch, and induction offers superior repeatability with no open flame and delivering heat only where it's required...

Brazing brass tube and fitting assemblies

The brass tubes and fittings heated to required temperature far more quickly than with customer's torch method, resulting in improved part quality and introducing less heat into the production environment...

Brazing carbide tips to a steel cutter

The cutter was held in a vice and the coil was presented to heat the assembly. A ceramic rod was used to press the carbide tip onto steel cutter during brazing.

Brazing a carbide ball to a spring to create a part that controls the armature position in a motor

To heat a tungsten carbide ball and steel rod that acts as a spring to 1300 °F (704 °C) within five seconds for a brazing application to create a part that governs the armature position in a motor...

Heat a steel block with a cutout for carbide for a brazing application

Induction delivers improved quality and repeatability; client was using a torch and induction offered more precise, repeatable heating. In addition, this allowed the client to achieve the targeted heating time of 60 seconds, faster than what the torch could deliver...

Brazing carbide insert to steel pipe gripper chuck

Induction heating is proposed to braze carbide inserts into steel blocks in the assembly of pipe gripper chuck. To replace a hand/flame process, delivering significant reduction in per-part cycles...

Brazing a stainless steel shaft to a carbide for a digger used in mining

A three turn helical coil is used to braze the carbide to the shaft. The steel shaft is fluxed and the braze shim placed on top. The carbide tip is fluxed and placed on top of the shim, lining up the countersunk hole in the carbide. The hole is not fluxed because the flux outgases and causes the carbide to build up pressure and attempt to repel from the shaft...

Brazing a stainless steel shaft to a carbide cone for a gripper

A three-turn helical coil is used to braze the carbide to the stainless steel shaft. A silver solder washer is placed over the post on the shaft, the carbide is placed on the washer and flux is applied...

Braze a carbide tip to steel cutting tool

A split helical coil is used to heat the carbide & circular steel cutter evenly for the brazing application. The circular steel cutter is placed in a vise and the carbide and braze shim are placed onto the tooth...

Braze a diamond carbide tip onto band saw blade

A single turn helical coil is used for this brazing process. The saw blade and diamond carbide tip are placed in the coil...

Brazing carbide teeth to steel pipe jaw section

Induction heating provides hands-free heating that involves no operator skill for manufacturing, consistent, repeatable aesthetically pleasing brazes with even distribution of heating

Shrink Fitting Hammer Bits

Shrink-fitting hammer bits with induction for the insertion of carbide buttons; the end product is a drilling tool for the oil and gas industry.

Brazing a carbide and steel shank for a plug guage

Induction heating provides hands-free brazing which requires no special operator skills for manufacturing, precise, even heat is applied and is divided equally, between the shank and the carbide, providing an even flow of the braze alloy as the parts reach brazing temperatures.

Steel-carbide brazing cutting tool

The body shim and carbide are cleaned and braze flux as applied to the entire surface of the assembly. The parts are placed together in the induction coil.

Brazing carbide to steel for a surgical device

Compared to a stick-fed flame braze heating, induction heating provides consistently higher quality joints. This is critical for medical applications.

Brazing Carbide Tips to a Meat Cutter

Due to the size of the induction coil, the process allows for precise placement of the carbides on the steel shanks

Brazing carbide rotary file to high speed steel shanks

A multi-turn helical coil is used. The part is heated to determine the time required to reach the desired temperature and required heat pattern. I

shrink-fitting a carbide ring into a valve seat

A three turn helical coil is used to heat the steel valve seat. The steel valve seat is placed in the coil and heated for 50 seconds to enlarge the center hole & drop the carbide ring in for the shrink-fitting process.
