What Tungsten is used for Titanium Tig?
[From PWL#071, Section 3] As it is widely known, available tungsten electrodes used in Gas Tungsten Arc (or Tig) Welding can be made of a few different types of powder metal compacts. For Titanium welding the conventional thoriated Tungsten electrodes known as EWTh-1 and EWTh-2 are used (with 1 or 2%Thorium respectively), ground to a point. Welding-titanium is done with straight polarity direct current (tungsten electrode connected to the negative pole). See also Welding Titanium. Welding Lead [From PWL#073, Section 3] The following comment was sent by Mr. Timothy Lynch President of Kenneth Lynch & Sons from the United States. Date: 12 Aug 2009 Sir: I read with interest your treatise on welding lead. Well done, except that we use oxygen and hydrogen mix to weld lead (statuary). The reason is that oxy-acetylene will cause the lead puddle to “pop” or blow out, sometimes causing burns if the spatter lands on your skin. This never occurs with oxy-hydrogen mix. All other problems remain as
