Requirements for burrs in energy storage welding

Do Welders use carbide burrs?

Although some welders rely on carbide burrs more often than others – depending on the level of experience the welder has or the applications they’re working on – it’s important to understand that they are much more than a commodity-type product.

Why are burrs a problem in machining?

These undesired and unwanted materials often come in many different shapes and forms depending on machining process and work piece materials. This burr formation causes reliability problems on the parts and degrades their performance [6, 7].

What are the stages of Burr formation in drilling operation?

While burr formation in drilling operation may differ in grinding and milling process, their formation mechanism can also be divided into four stages such as initiation, development, pivoting and burr formation . Figure 7 presents the steps of burr formation based on three-dimensional simulation of drilling of 304 L stainless steel.

How to reduce burrs after machining?

Burrs can be minimised by selecting proper tool geometry, tool materials, coolant, machining parameters, work piece material, process planning and tool path design. As there is no method that can eliminate burr formation, thus deburring is essential to eliminate burrs after machining.

Do process parameters for electromagnetic heating affect Burr morphology?

The correlations between the process parameters for electromagnetic heating and burr morphology are disclosed quantitatively by expounding the extrusion welding process for welded pipes under electromagnetic heating for the purpose of exploring the welding quality characterized by burr morphology under different process parameters.

What types of burrs are formed in drilling operation?

The burrs that formed in drilling operation can basically be grouped into several types such as uniform, transient and crown burrs. Uniform types of burrs, which are often of two kinds (with and without drill cap), are shown in Fig. 12. The mechanism of formation of this kind of burr is presented in Fig. 13.
