Welding slag can cause problems when welding but it also serves a purpose The slag is created by the melting flux coating during welding Once it melts the slag should rise through the weld pool and forms a shield across the top of the weld pool that protects the molten metal from contamination and oxidising atmospheric gases
Note Some bacteria possess enzymes other than catalase that can decompose peroxide a few tiny bubbles forming after 20 30 seconds is not considered a positive test Quality Control Each new lot or shipment of the reagent should be tested with positive and negative control before using them A Staphylococcus aureus ATCC 25923 catalase positive B
