Now a days we came across hearing plenty of NDT training centres are offering NDT level 2 in Basic NDT methods like RT, UT, MT, PT etc within a duration of 15 days on 2- 4 hours training session per day.We are posting this article here for making aware the general public about the facts on what's NDT and How can be it acquired.Does'nt matter which training centre major factor shall be is there worth for what you pay and will it be recognized in industry and also will it be useful for the certified person because it's your hard earned Money is paying for each and every training programNormal NDT programs offered by Institutions are based on ASNT SNT 1A practice standard and which are accepted world wide if it's properly delivered.As per ASNT published minimum training requirement each individual candidate should get a Minimum training hours for practical and theory for each method Eg: Ultraosonic Testing direct level 2 requires a Minimum Training hours of 120 for progr…
Comparison of the use of rutile and cellulosic electrodes
Types of electrodes and their compositions
Many types of manual metal arc (MMA) electrodes are available on the market. Depending on the main constituent of their flux, they are grouped into three categories: cellulosic, rutile and basic. All electrodes consist of a cored wire (typically 2.5–6mm diameter) coated by a flux. The core wire is generally made of low-quality riming steel and the fluxes contain many elements allowing refinement of the weld macrostructure.
The composition of the flux impacts the electrodes’ behaviour. The main constituents of the different types of electrodes and the shielding gas created for each are described in Table 1 (Bowniszewski, 1979). Table 1 Main constituent of the three possible types of electrodes and shielding gas created by its combustion.
