The most common shielding gases used for these main arc welding processes include argon (Ar), helium (He), carbon dioxide (CO2) and oxygen (O2). While Ar, He and CO2 may be used by themselves (i.e. 100%) for certain applications, in other cases the four gases are mixed together in different combinations to form shielding gas blends.
Cluster reduction in speech is when a consonant cluster, that is two or three consonants occurring in sequence in a word (like ândâ in friend), is reduced by a child into a single consonant through omission.
Really, whoâs going to understand that?? What youâre experiencing is called final consonant deletion and it can make a child VERY difficult to understand. Young children typically do this to make speech easier to say but most kids figure out how to use final consonants by 3 years of age. Children who continue to use final consonant deletion past 3 years are considered to be atypical and should see a speech-language pathologist for therapy. So what do we do about final consonant deletion?
