Reasons for spatter
Spatters are small particles of the molten material which are dropped on the welding surface after being generated at or near the welding arc. Spatter is caused by several factors. The prime factor being a disturbance in the molten weld pool during the transfer of wire into the weld.
Why removal of spatter is important yet difficult/ detrimental by conventional methods? Problems Associated with Spatter.
Removal of spatters has always been the most important aspect of post weld operation. There are however a number of problems associated with the conventional methods of chipping and grinding. Some of the associated problems has been listed as under: #1. Incomplete penetration, undercut, pores, slag inclusions, weld spatter and arc strikes are typical examples of weld defects. These defects have negative effects on mechanical properties, resistance to local corrosion and make it difficult to maintain a clean surface. #2. In the case of stainless steel which is protected by a layer consisting mainly of chromium oxide, the surface defects leads to its removal and therefore corrosion. Therefore a fine surface finish is crucial to corrosion resistance. #3. Grinding or blasting too heavily will result in rough surfaces. A rough surface collects deposits more easily, thereby increasing the risk of both corrosion and product contamination. #4. Heavy grinding also introduces high tensile stresses, which increase the risk of stress corrosion cracking and pitting corrosion. There is a maximum allowed surface roughness (Ra-value) for many applications, and manufacturing methods that result in rough surface. #5. Otherwise, pickling is the most common chemical procedure used to remove oxides and iron contamination. But the effectiveness of pickling also depends on the surface which must be free of organic contamination.
Metallurgical aspects of welding and the use of flux.
Let us understand the metallurgical aspects that are involved during welding and how welding flux works. Also, we will look at the process by which Spatter Cure helps refine the weld melt. Generally the steel contains 0.01 to 0.02 % oxygen; whereas, the oxygen content in the weld melt is as much as 0.2 to 0.3%. This excess O2 has an adverse effect on the mechanical properties of the weld metal, especially impact strength, besides formation of more FeO. In high-temperature metal joining processes (welding, brazing and soldering), the primary purpose of flux is to prevent oxidation of the base and filler materials. Flux prevents the formation of metal oxides. Additionally, flux allows solder to flow easily on the working piece rather than forming beads as it would otherwise. O2 contents in the weld metal varies with arc length, welding current and the type of shielding employed. The coating of the electrode promotes a shield of slag that is not adequate, even with standard quality of electrode, to have lower level of oxygen in the metal. Contact of air with the weld pool may also increase the nitrogen content in the weld melt, which is very harmful. These gaseous inclusions are responsible for bringing down the impact strength of the weld metal, which in turn causes weld failure.
How Spatter Cure SC-07 works in the refinement of weld melt?
The coating of Spatter Cure SC-07 in the V -groove helps to address the imperfections in weld-ment. In the weld pool, the coating acts as a flux. Thus when the arc is formed, this coating develops a film over the weld metal protecting it from the surrounding air that is by and large very active and hence the possibility of contact of the weld metal with oxygen and nitrogen of surrounding area is minimized. Thus, it helps to get a clean and dense weld with improved mechanical and metallurgical properties. Apart from protecting the weld pool from the surrounding atmosphere the coating (here it acts as a flux) partly removes oxygen from the molten metal because of the presence of De-Oxidizers in the compound. The oxides, being lighter than metals, formed by de-oxidation of the weld pool floats up and are removed along with the molten slag.
